Is anyone here using "pure talk" (att mvno) or "red pocket" ? - Xiaomi Mi Max 3 Questions & Answers

Hi there, I've got my (rooted) MI max 3 Volte & wifi calling working with the ATT variant of Tracfone and want to switch to a different ATT MVNO (loved Teltik/ TMO but neither worked and calls intermittently went straight to VM on 5 bars reception)
I'd love to use Pure Talk if poss since they have a good rep rep and I hate ATT prepaid customer service... Tracfone is also bad. And I heard Red Pocket porting can go horribly wrong sometimes.
If you have Pure Talk are Volte and wifi calling and MMS all working consistently? I also have a Redmi Note 5 (Whyred) I could use instead of Max 3 if I must.
I have seen reports stating that even though they use ATT Towers these features don't always carry over when people switch to Pure Talk.
(Not really an XDA topic but there weren't enough Xiaomi users in Howard Forums and the Pure Talk rep on Reddit didn't know)
If you heartily recommend some other prepaid ATT MVNO I'd love some tips. I'm a light data user, don't require Int'l, want tether and wifi calling for emergencies
Many thanks!

[Q] Straight Talk - At&T vs T-mobile Questions

Hi all I have a few questions I am hoping someone can answer. I currently have a At&T i717 Note I am using on Straight Talk with a AT&T sim card.
I am getting ok speeds with it and good indoor building coverage. It is unlocked and I had been using it on contract with T-mobile with much better speeds but I couldn't use it at work being in a concrete hospital low building permeability. I am now trying to decide which Note II to buy that will work for me best.
My questions are as follows:
1. Does the Note II use mini sim, or nano sim like the iphone or normal size like the Note i717. Currently Straight Talk only offers mini sim cards for At&t coverage map and not T-mobile (yet I am contacting them to see if they are planning on offering this).
2. Is it difficult to cut down a sim to be the correct size for the Note II if I do want to buy the T-mobile Note II and use it on Straight Talk (faster speeds in my area).
3. Will the AT&T Note II have the ability to be unlocked and used on HSPA+ on Tmobile with flash of different modems like the Note I was modded to do (or without modding)? Or are the radios/modems already compatible on both At&T and Tmobile HSPA+ networks.
I am kinda confused and unsure of what I should do. I want to sell my Note i717 and use the money for Note II but don't want to make the wrong decision between the two options I have listed. I may end up going back on contract with Tmobile with a family member but I would like not to.
4. One more question not specific to the Note but does anyone have any input on credit checks and down payments for AT&T, I have poor credit from when I was younger and made some stupid financial decisions but my job offers 22% discount for AT&T plans which it would be nice for me to take advantage of being able to then use LTE. It would be a $50 on Straight Talk vs. $75 on AT&T (LTE). I probably would be willing to pay the extra $25 a month if I don't have some outrageous down payment. I will check with AT&T directly when I can but was looking for any input from fellow Note II lovers.
Thanks in advance for any help!
IMPIMMS (AMANDA)
I am currently using the unlocked note 2 on straight talk. I tried to cut down my regular sim ti micro but I failed. So I ordered a new micro sim from straight talk. Speeds are good as is coverage. Average about 6mbps+ Sadly I dont know the answers to your other questions.....hope this helped!

Don't use T-Mobile
I recently signed up for Straight Talk. Since my phone was an unlocked T-Mobile phone, I ordered a Straight Talk SIM. My service is horrible. I rarely get 3G, mostly edge. Even the cell service is poor. I have put a non Straight Talk AT&T SIM in my phone and get a constant 3G. So I have ordered a Straight Talk AT&T SIM; will start using the first of November. Hopefully the bad service I have received is the T-Mobile SIM and not Straight Talk.
Just a heads up I was using my note on straight talk and I wanted to use the SIM in my note 2. The people at my local T-Mobile store were nice enough to cut the SIM for me even though I was not using their service. A lot of their stores have SIM cutters for people who are trying to run iPhones on their network.

Thats because the unlocked international verion of the phone will only work on the HSPA+ that ATT and Stright talk both have. Consider yourself lucky to see a 3g Signal if your on Tmobile because from my understanding it only works on EDGE with Tmobile:highfive:

It has been posted all over this forum that the international version of the Note 2, if used on T-Mo will only get Edge data in 99% of the nation. The only places where you will see 3G or H+ is in those areas where T-Mobile has already refarmed its 1900 MHz spectrum (because that's the band that the international Note 2 has). I have heard some parts of Washington state, Las Vegas, Chicago and NYC have it.
But if the OP buys the T-Mobile variant, he would be able to get H+ at very good speeds (depending on where he is).
I'm kinda in the same predicament as the OP... I'm using an original at&t note with an At&t straight talk sim card. I would love to go down to tmobile tomorrow and pick up a Note 2 .. unlock it and throw my sim in it.. but will it work? I can wait till Nov. 9th for the At&t version but if they will work the same I'd like to jump on it now.
Does LTE work
I heard it works with Att LTE is that true can anyone confirm?
Ive heard the note 2 for tmobile is the exact same hardware as the at&t. Not sure how accurate this is, i got that from tmonews. So the tmobile variant also has lte support but is disabled i believe.
That being said, if they are the same harfware with just different model#s to identify the carrier, i would think the at&t version should also have hspa compatible with tmobile, but might just be disabled. Again, this is based on what i read in tmonews.com regarding the tmobile version.
Hope this helps
Hey guys,
Not trying to hi-jack this thread but I have a similar question:
I had Windows Phone on the ATT network. I switched to Straight Talk a month ago by just switching out the sim cards. The phone & service worked great except straight talk does not support windows phone because you can't edit the APN setting in Windows Phone because they are automatic. It was time for a new phone anyways so I went on ebay and found a new phone unlocked on the T-mobile network. I put the straight talk sim in the new phone and now I am getting a lot of problems with sending & recieving text etc. The major problem I have is I keep getting a text message that says +1121611611 (2288 Error Invalid Number, Please resend using a valid 10 digit mobile number or valid short code. This is continuous day & night and will not stop and runs my battery down. Is it possible that I can't use a T-mobile phone with a AT&T version Straight Talk sim?

Well that explains why I see 3G in Seattle.
I plan on switching to straight talk in April I want to get a note 2 but I have 4 problems
1. Which company will offer the best service ATT or TM?
2. If I get ($$$) Phone is there a way to get insurance/Warranty that will cover me it in case ANYTHING happens? Would Square Trade Do it?
3. Will all the features work?
4. Which sim card should I get ATT, Straight talk or Tmobile?

First off, why dig up this old thread to post in, it's last post was in October. But I do have to thank you because you obviously did search first.
TMobile is out of the question if you are looking to buy an international Note2 (N7100). You will be only able to use 2G on it unless you are in one of a handful of cities. So if you want to use TMobile, your best option is to buy a TMobile version of the Note2.
As for if you should use TMobile or ATT, no one can answer that for you. You have to talk to people in your area about how their service is, dropped calls and data speeds. As a general rule ATT has better nationwide coverage but there are many places where TMobile has great service and data speeds too.
Insureance, how many times have you dropped your phone in the last year? I put a TPU case on my Note1 and dropped many times and never had it break but some people have them break on the first drop. Up to you, I think it's waste money.
Would love to know if the att note 2 will get lte if on straight talk

tmobile note 2 contract is up, can I go no contract with it?
I have a note 2 that I got when I was still under contract, im curious if I can go monthly no contract and still use it. Probably through t mobile still until something better comes along, so I don't have to be locked in a contract. Because it sucked.
I have Note 2 N7100. International unlocked version bought from Newegg in Nov of 2012. I have used Straighttalk (AT&T SIM) the whole time. I have had them cut off my data twice so far because of TOS. Says you cant stream music/video, use P2P, and other crap. Basicly they say you can only browse. But let me be clear, I was using 5GB+ each time they cut me off so yea, it was my fault, I know what unlimited means and it's unlimited. Each month they cut it off, I got it turned back on no issues. Now for the last month, my speed has bee HORRIBLE all month. I have used under 500MB thus far but its bad. My wife, who has Nexus 4 and uses a concistant 500MB - 1GB/month and has her ST account totally seperate has the same issue. So does my neighbor and two co-workers, we are getting horrible speeds for the past month or so. So I am seriously concidering AT&T thier ungoddly bounty for service starting next month. I get a discount at work so it equals out to about $70/month, same as the others. I loved ST but it's gotten really bad...
BTW, I bought a TM SIM from TM last week and it was 2G from work to home. I live in Birmingham AL. there is a few miles of good 3G on the interstate but thats it. Hope this helps
Straight Talk has lost out on AT&T for whatever reason(s). They don't offer the AT&T Sims on their site anymore. There are some left on eBay but the sellers have doubled the price or more. The day is supposedly coming that new AT&T Straight Talk Sims will no longer activate. ST has also downgraded the unlimited data on AT&T to 1.5 GB a month. Tmobile sucks in my area. I hope to never have to use it again.

http://androidheadlines.com/2013/02/straight-talks-unlimited-data-not-so-unlimited-anymore.html
so i recently just moved from boston to ohio (44820 zip) while i was in boston i used tmobile. however when i came to ohio i noticed i was always using 2g via att. tmobile has no service in this town. so heres my dilemma...i signed up with sprint and to be honest im (no 4g lte and 3g sucks) wanting to dump them. honestly i will pay the etf for both phones (note 2 and optimus g). i just want out!
so im trying to decide what to do...is straight talk or net 10 the way to go? do they both use att or tmobile. i have searched but if i understand correctly att runs net 10 and straight talk runs tmobile. but do they roam on each other?
any help would be awesome! i truly would love prepaid with unlimited data.
look up my zip and you will see tmobile is a no go. so now its att but which mvno and i need unlimited 3 or 4g...
thanks!!!

Wifi Calling With AT&T on N900-T Unlocked...Possible or not?

As I have experienced first hand, T-Mobile's wifi calling feature works amazing on my Note 3. The problem is, where I live, work and play we do not get any T-Mobile service above 2g, and mostly nothing at all. I'm actually confused as to why local stores are even selling the service. It simply doesn't work here. Anyhow, I had purchased a month of prepaid service with them because I don't get ANY service from any provider at my home (except Verizon, who comes in at 5 bars in my basement). The wifi calling feature was amazing for this one reason. I never missed a call, or text and life was good. Of course, the moment I left the house my $800.00 Note 3 turned into a very expensive makeup mirror for my wife because, like I mentioned, we don't get T-Mobile here, at all. I still have 2 weeks of the service active, and put the sim into my i-747 S3 for testing.
I'm currently running Hyperdrive RLS3.1 (NB4) on AT&T Go-Service on my Note 3.
What I'm asking is simple, or maybe it isn't -
I would like to know where I could find info on a REAL wifi calling service. Not these 3rd party apps that give you a new free #, etc. I'd like something that integrates into the phone, like TM Wifi calling does. After searching this topic on XDA, I found a few threads on SIP VoIP. I'd even be willing to give that a shot. If I have to invest a few dollars, that is also ok. Has anyone else successfully done this? Any better idea's or suggestions? I'm tired of not being able to make calls from my cell phone at home. I have looked into repeaters, extenders, etc, but that is for another thread, I suppose.
I know that the native wifi calling on my Note 3 will not work with AT&T, but there must be something that can work....
Thanks for any info or help anyone can provide.
Real WiFi calling has to be supported on the back end by the carrier.
You are going to be limited to a 3rd party solution.
That's what I use. I have to use magic jack.

I also started using magicjack on my phone. After trying out several voip SIP services with the native android app, I realized that it would never have the sound quality I needed.
This is all null and void now though. I retired my N900T and bought the Verizon Note 3 and never drop signal or lose LTE, even in my basement.
100% not possible. It relies on servers at T-Mobile's end. Plus the settings in the Wifi Calling app are set to T-Mobile's servers on top of that.

Sprint - Data and Phone Call Simultaneously?

I finally upgraded from my HTC One M7, and I can't make phone calls and surf the web while on 4G anymore! I did a little Googling and found out it's because Sprint's Spark network doesn't support VoLTE. And from what I'm reading, it seems like Sprint phones only have one radio.
Is there a way around this? Does the HTC 10 for Sprint maybe have all radios, but they're disabled and you can gain access with root? Maybe I can do away with LTE and just go back to classic 4G & CDMA?
Thanks!

Right now Sprint does not support VoLTE with any of their current devices. Sprint put all of their time and effort into the Sprint Spark project. When Sprint started the Spark project they needed their devices to be Tri-Band devices which in turn removed the ability to use voice and data services at the same time. The HTC 10 is a VoLTE certified device and is capable of WiFi Calling as well with other carriers. Based on an article I read earlier from www.S4GRU.com, the only device that Sprint has that is VoLTE certified with the FCC is the LG G5. If you want to be able to use voice and data services at the same time with Sprint you will have to use an older device like your M7 that is not a Tri-Band device. Another Sprint device that can use voice and data services at the same time is the Galaxy S3 (SPH-L710) and the early
S4 (SPH-L720). If either of those devices have a "T" at the end of their number it means they are Tri-Band devices. Hope this helps. I feel your frustration with Sprint and VoLTE. My wife and I have been with Sprint for iver 15 years and have a grandfathered unlimited data plan that she wont get rid of. So, when the Galaxy S3 from Sprint made it to the end of its useful life with me I switched carriers so i could have VoLTE and my wife can keep Sprint.

You can achieve voice and data with Google's Hangout Dialer. The call is placed over data so you can use data during the call. Granted, you need to set up a Google voice number, but it achieves the purpose.
This is the reason I ditched CDMA all together and went GSM. (My MVNO has both, so it was an easy switch.)
Getting far better data rates (cable speeds rather than dial-up speeds) with a weak signal was an unexpected bonus.

WiFi Calling and VoLTE and AT&T

It's my understanding that these features (advanced calling, like WiFi calling and VoLTE) Doo not work on unbranded devices like Pixel and others. This was the case with my unbranded SM935F or Galaxy S7 Edge until we got some files, an appropriate CSC, and also had AT&T switch our account to an IMEI of an AT&T branded device that had working WiFi Calling (others have apparently just called AT&T and had them provision WiFi Calling)
Note: for me, I have a business account so I could just go into my business portal and put in an IMEI that I got from an S7 Edge model in an AT&T store
I am attaching the files that we needed to add to our system to get WiFi calling to work on AT&T. I think I remember all I had to do was to add them and make sure permissions were correct
Here is an IMEI that I saw on another post that may work ..... But I do know that the AT&T system needs to recognize your phone IMEI as an att branded device that has working WiFi calling. So if you aren't business customers it will require a call to customer support.
Possible working IMEI:
Mod edit: Removed
Any Pixel AT&T users that could try this and report back would be greatly appreciated!
Btw, I'm not completely sure which files are needed in the Pixel as compared to the S7 Edge .... I would have a backup available

I obviously could be wrong ...... But I'm 99% sure that what you are saying is not true for AT&T and maybe even other USA carriers!
I KNOW that I'm right for S7 phones and ROMs .... And the problem is so pervasive that they have even been able to get unbranded S8's to obtain WiFi Calling on AT&T or other USA carriers (even though WiFi calling works great on branded S8 phones)
AT&T users a different mechanism to provision WiFi calling than other carriers

You are correct that AT&T does not allow unbranded phones to use those features. It's all BS too. I have great LTE coverage but many times I will go to make a call and have crap service because they have canabalized a lot of the hsdpa towers for LTE. Then the switch back to LTE can take forever. And I don't care what they or anyone says AT&T's hspa+ is no where near as fast
None of this works, as AT&T blocks access to VoLTE on Pixel phones. Denies me the use of Numbersync for my tablet and android wear 2.0 watches. AT&T service techs keep promising to fix it and try to force it to work, but still blocked. It is simply a situation for Google to get the Pixel certified for the AT&T network, which is problematic, as AT&T uses a non-standard protocol for HD Voice that is unique to their network. So, as best I can tell, AT&T has to release the source code, for a price, I presume, to Google to add to the phones and then pay for the certification process with the FCC. Seems a stand-off as long as Google has an "exclusive" arrangement with Verizon. So for me, I'm pissed not to have numbersync for my devices, but unwilling to give up all the advantages of the Pixel phone.
That's why I switched to T-Mobile.

I doubt it. They only support advanced features on devices sold by them so it's not as if older Pixels will suddenly be grandfathered in just because they start carrying newer ones.
This annoys me to no end... If I buy a phone from att, do they have to give me an unlock code when the phone is paid off? I really need WiFi calling for a trip I make multiple times a year

Yeah according to a rep I spoke with, the pixel 2 will support Numbersync even though att isn't selling them. There are, however, no plans to change the restriction on the original pixels.
I'm in the same boat but I'm genuinely curious - if I don't need wifi calling - is it really a big deal not having VoLTE? I'm taking in terms of better signal or faster LTE internet speed. Or does VoLTE is just having clearer phone calls? I guess what I'm asking is what other benefits are we losing (on a technical standpoint)

Late response but as far as AT&T goes besides VoLTE what I experienced on my Pixel XL was random issues with group text (MMS) reception from certain individuals from other carriers.
In particular it seemed as though if senders of MMS texts to a group chat that I was participating in sent a text from a carrier like T-Mobile and they were using Samsung devices with VoLTE and enhanced LTE stuff enabled on their end I'd not receive the text. I would instead receive texts from others in the conversation. I could freely text any of the same individuals in a separate standard SMS conversation just fine, and they could send me an MMS text like a photo, but as soon as we were in group MMS I'd lose the ability to receive their texts and no amount of APN changes or combinations of texting apps would fix it.
I can't tell you how many times over the course of the first 5 months of owning my Pixel XL with an AT&T SIM in it I missed out on half the conversation in group MMS. Doing nothing to my phone other than porting number to T-Mobile and putting in my new T-Mobile SIM all of my group MMS issues went away (replaced with ****ty signal LOL but that's a different story). I'm now on Verizon with my XL and am a happy camper, albeit poorer having wasted money jumping around.

ATT Wifi Calling on Pixel 3 XL...shouldn't we be able to enable it on the 2/XL?

Someone has confirmed wifi calling working on the 3 XL on ATT, if that's true shouldn't we be able to get it working on the 2/XL? Is it IMEI related? Even if so, if I were on a rom that had wifi calling and swapped a sim in it from a Note 9 or something it would work at least until the system detects the imei and updates it, which isn't always the case or all that fast to happen.
Sounds like a carrier issue.
I think it's garbage that At&t ran this whole campaign "Google Pixel works on At&t" yet they won't release all their features to the users. I had to beg them for HD calling. Finally after a week they activated it. This stuff should be automatic and available to everyone. I pay the same amount as an iPhone user
This has me sitting with mixed feelings. I have really bad AT&T reception in my basement and really need WiFi calling. I don't want to spend so much money upgrading from a 2 XL to 3 just for this though.. (granted, I like the non-XL 3 form factor better..)
Seems like poor customer perception to enable this finally on the 3 phones when the 1 and 2 fully support this other than AT&T flipping a switch on the other end. I'm glad they finally are allowing the 3s.. but..
