[Q] G2 and $5.99 Tzones

I have a T-mobile G2 with grandfathered $5.99 tzones. My internet worked for few hours the first time I put my sim card in, but now I keep getting service unavailable error message. If I switch phones and put the sim card in Nokia e71 internet works just fine. I am sure if I call T-mobile they are going to say I need one of the android plans.
I have tried all apn's: epc.tmobile.com, wap.voicestream.com, internet2/3.voicestream.com. No luck so far.
Any ideas if there is anyway I would be able to use tzones with G2?

Nope, you have to to be on a android data plan to get your data service working.
You can call up T-Mobile's retention department and ask them to put you on teh preferred android plan for $20 (as oppoes to the $25/$30 plans)
The reason you cant use the 5.99 plan is because the phone's IMEI gets picked up T-mobile's servers and finds it as a ANDROID phone, thus requiring you to get the proper data plan.

Thanks for your response. Do you think rooting the phone will make any difference?

Rooting wont make any difference, Tmobile knows you have a G2 based on the IMEI of the phone.
There is no getting around an android data plan, the best option you have is going to retentions and getting on the preferred android plan for $20

aaah... Not the answer I wanted to hear, but I guess I will have to deal with it.
Thanks!

just an option, when i used that data plan on my iphone i just kept changing the apn til i found one that kept working.
so open ur apn option and just start trying stuff.
with the tzones plan we used epc.tmobile.com, on a friends we used internet2.voicestream.com, or internet1.voicestream.com, or wap.voicestream.com. its not designed to work but with the right apn it just might. i doubt you'll get the hspa+ speeds tho

iPhone is different, it doesn't even support the T-Mobile 3g band. I don't think you'll have any luck with changing apn's...

I tried that. None of the Apns work.
Once interesting thing I noticed is even if I change the apn name to epc.t-mobile.co it still gives me same error message with the web2go logo "service unavailable". If there is invalid APN name it should give me a different error I would have thought.

the only way to get the G2 to work with tzones is to buy the G2 through a carrier other than tmobile (which probably means getting a Desire Z, not a G2)
T-mobile only knows that your G2 is android phone because it has their logo on it (and therefore in their database)

If I import a G2 from Tmobile Europe, will it work on Tmobile USA tzones?
Does Tmobile USA also have the IMEIs of its European counterpart?
Edit: Desire Z doesn't use AWS. Europe doesn't use AWS.

Unable to connect LG G3 T-Mobile phone to networks in Europe

I recently brought my LG G3 with me to Europe (while on Honeymoon) because I found out from T-Mobile that I could use text and data there at no extra cost. My phone works fine in the United States. But it doesn't find a carrier connection in London; Southampton; Vigo, Spain; Lisbon, Portugal; Cadiz, Spain; Gibraltar; and Barcelona.
I tried my phone in each location and it never connected to anything that wasn't WiFi. That really really sucked. I get that I have it rooted and I am using a different Lollipop ROM than stock. But I didn't think that would prevent it from connecting to towers there.
So what happened? What would be on a fully stock T-Mobile LG G3 that I wouldn't get on my rooted and ROMed version? I'm sure it something simple, but I would really like to know so that I can fix the problem before I go back.

did you turn on roaming?
mine worked great in Paris.
also, if you have really older version of rom
http://forum.xda-developers.com/tmobile-lg-g3/help/international-roaming-g3-t2834451
you may need to do this

Worked for me in Paris and Lisbon. I've had some issues when wifi calling is enabled, though. I think there are some very real modem issues but I eventually got it to work.

AT&T LTE data issues on Verizon LGG4

I have been trying to use my verizon LGG4 on AT&T, I don't have an issue with call and messages but the data is not working on LTE, I have been upgraded to 13B and haven't rooted yet as the other forum suggested for T-Mobile, but I haven't seen any specific solutions for AT&T.
I have tried to change several options on Mobile network for data and APN setting but nothing is working.
Can I have any expert help on this.

If you look at the T-Mobile thread, there is also a lot of discussion regarding AT&T/Cricket. AFAIK, there is currently no solution for AT&T, so you are stuck on HSPA currently. I ditched Cricket and went to T-Mobile, works like a charm now with great speeds. I realize that may not be a solution for everybody, but I have my doubts a solution for AT&T is possible, at least on the current firmware.

I'm about to buy a Verizon version for super cheap that's unlocked for my at&t, does mms work? And is your H+ fast? Could u do a speed test and post the results? I just don't want to waste my money.

Cricket canceling 7T on their network?!! As of Feb 2022

I made a call and got a message that my phone would no longer work on their network since they are upgrading things. This phone isn't that old. I wonder if their system doesn't recognize it. The lady said their system was showing it was a 2g phone so I told her it handles 4g. She said on Cricket it's only able to use 3g. Does anyone know if this is true. I don't trust some operator in another country reading off a script. It sounded like they want everyone to buy phones from their website. I can't imagine a relatively new phone not having the right band. Maybe there is a setting I need to tweak or flash onto my phone if I'm only using 3g on Cricket. I'm sure I've seen my antenna say LTE. Or maybe Cricket is screening out non Cricket phones.

Check it's specs.
If it supports the needed 4G bands it may need to be reconfigured. I haven't a clue how to do that.
Maybe Access point names but it may go deeper than that.

I'm going to google and see exactly what specs Cricket will require. I think you're right and maybe something to reconfigure. I can't imagine Cricket shutting off tons of new ish phones just because they aren't bought from Cricket. Ran a speed test now and got 2.77mbps download and 8.49mbps upload. I am showing LTE now which means I'm not on 3g as she was saying now. I bet it's a sales gimmick to scare less savy folks. What mean loose phone signal in Feb hehehe.
Edit: I was on wifi when I got the message so maybe when I phone is on wifi and not using their LTE network it doesn't detect anything which is why they told me I have a 2g phone. When I shut off wifi LTE popped right up so it's probably a glitch in their way of informing us.
Edit2: Spoke to a tech at Cricket and he said my phone currently isn't compatible with them aaahahahhaha dumb. I told him I'm currently using it on LTE just fine no issues. He didn't have anything to say when I asked him since I'm not using 3g then it shouldn't affect me. He just said he wants me to have great service so buy another phone from Cricket. BS

I have HD1907 and it's currently working on LTE. Are you referring to not working in the future or currently working?

Not working in the future. Here is the list of devices can work after Feb 2022.

Yes I was able to download that list when I googled. Judging by what it said these are phones that are tested and will work, not so much that other phones won't work. My phone was originally branded for Tmobile so I'm sure they wouldn't have tested it but it would have only had a different OS with Tmobile bloatware which I took off. The cricket people said their LTE isn't changing so I shouldn't have an issue but it will be interesting to find out. They must have just been looking at this list which is why they said my phone currently isn't compatible.

Funny this was asked but no answer given from ATT. I'll keep googling

I read a discussion here from 2019 someone else asked and the different variants are by region as they usually are for the different LTE frequencies. 1905 is North American, 1907 is Tmobile in North America so I would imagine my LTE frequency is still going to be fine. Those that bought Chinese phones etc probably not.

This is weird. The current ad for it on Amazon says it's currently not compatible with ATT and Cricket. I wonder if me flashing another OS for North America or USA I forget is why it works fine? Maybe I'm screwed hehe
*** NOTE: Due to changes with AT&T and Cricket, this phone currently cannot be used on AT&T/Cricket. Compatible with T-Mobile and all GSM Networks along with their compatible MVNO networks such as Red Pocket GSM, Ultra Mobile, Mint Mobile, Ting GSM, Google FI and many others. This phone is NOT compatible with Verizon, Cricket or AT&T. Please verify with your network to ensure complete compatibility.

I work at a prepaid carrier store (not Cricket) and am having to tell customers the same thing. It's not just about if your phone has the radios necessary, they have to have the IMEI approved in their system and if it's not then you can possibly escalate to someone who can help get it approved but you probably won't get very far. I can't activate my own OnePlus device with my company either, even though it's currently running on our parent network. I have spoken with internal support folks about it multiple times and have gotten nowhere so I gave up.

Believe it. It sucks and it sounds insane but it's really happening. For me? I have to tell everyone with a Samsung Galaxy S5-S10 that they have to buy a new phone to be compatible with our new network changes. And I can tell you here that it's (probably) not the sales rep lying to you to make a commission sale, our tools are indeed forcing us to do that.

I'm just wondering why they are saying my phone currently isn't compatible when it obviously is. It works great. Even streams HD in an instant on Crickets network. Corporations aren't super efficient at checking all things under the sun. They are just checking phones they approve. They told me the same thing that my imei currently doesn't work but it does. Unless they are trying to be like Verizon and only allow specific phones in the future I'm still thinking once they shut off 3g then when someone wants to switch from Tmobile to Cricket with their unlocked working fine non 3g phone they still can or are they saying no they are going to be like Verizon and it has to be a Cricket branded phone. I don't think it's the later. I think they are just saying what will work, but not saying what won't work. Let's find out =( hehe

Read a discussion from 8 months ago. Seems like most are fine, one guy with a 1905 had issues on ATT. One guy did what I did so maybe that's why mine is fine for now. I haven't had issues like dropped calls etc but maybe the real issue I will have if Cricket adds wifi calling and VoLTE is if they use a specific frequency and the 1907 is missing it then I won't be able to use those. If Cricket only uses VoLTE then yes I am screwed in February =/

"I am currently using a 7t that was advertised as factory unlocked on ebay, when it showed up and I turned it on the big bright pink Tmobile boot logo came by. I did some research and found the convert to international/global thread on xda, I got rid of the crap hydrogen OS that came with the "unlocked" Tmobile phone. Using ADB I was able to flash the international firmware Oxygen OS and haven't had any problems with at&t now."

If it's an IMEI issue, flashing with the hd1905 fw probably won't help matters. I have a hd1905 on cricket since 2019, everything but wifi calling works. The same cricket sim in a samdung s9+ yields working wifi calling.
So while the hd1905 and 1907 are essentially the same hardware devices, the serial #/imei may determine what happens come 2022.

Yup, I'm wondering if the hardware or the IMEI will determine things. I didn't even know Cricket had wifi calling. Did Cricket even let you download the wifi calling app but it didn't work or did they not allow you to download it?
Edit: I looked it up. Looks like wifi calling will work on phones that have it built in to their OS settings. I probably won't use it if I end up buying another OnePlus phone. I wonder if there are any phones where wifi calling is working on Cricket that isn't on the list but is in the OS settings.

Wifi calling app? The s9+ was hybrid flashed. Everything but the main OS came from the U firmware (carrier), while the rom came from U1 fw. Result was working carrier features (volte/wifi calling) without the bloat.

The s9+ is probably the same as the s9 as far as the wifi calling since "+" isn't mentioned on their list.

Huh? It's right under the s9.

Unlocked T-Mobile Wing onto AT&T?

I have an unlocked T-Mobile WIng (LM-F100TM) that has been working fine on AT&T for a couple of months until last Friday when the final switch was thrown removing AT&T's 3G network. Even though the Wing is capable of 2/3/4 and 5G, AT&T identifies it as a 2G phone and locks it out. Or it doesn't satisfy their model search (LM-F100VM is supported AT&T model, LM-F100TM is not on the list) and locks out. I'm about to throw in the towel having spent a couple of hours with AT&T support trying to find a workaround but thought I would try here first. I've tried using the hidden menu to change the RAT selection to just LTE and have enabled VoLTE and such but AT&T still rejects it as not compatible/not allowed.
Anyone out there think there is a chance of getting this phone onto the AT&T network as a 4G/5G phone or should I give in? Thanks.

It won't work.I have spent countless hours changing firmware that's available via download,and it just won't work.When the device boots and connects they have it set to look for what firmware version is currently on the device.If doesn't see the correct version for the AT&T model it blocks VoLTE from provisioning properly.I had a demo version,and I swapped the IMEI to even match a AT&T sold Wing and it was a no go.I finally broke down and bought a junk Wing,and swapped the board.The upside it being a demo model the fingerprint scanner works like it should now..lol..

Thanks for confirming my suspicions that it's a lost cause -- I'll be able to move on now and stop spending time looking for solutions that don't exist. Frustrating to say the least with AT&T's ad campaign of bring your own device but it is what it is. I was hoping someone with better phone skills than mine had gone through some reasonable attempts to make it work and it sounds like you did just that. Thanks again for your response.
