[Q] Droid incredible 2 verizon phone unlocked to t-mobile!!!!!!!!!!!

hi so i recentlly got a droid incredible 2 and unlocked it to use on tmobile. now my question is can 3g be enabled to use on tmobile network?
i have it working on edge so far but it love to take advantage of the 3g network . plz help!!

Congratulations, you have posted in the wrong phone forum. Also, I don't believe you would have access to T-Mobile 3g unless the Inc2 supported their AWS 3g bands.

figured id post in the wrong place and thanx il check out if it does support the bands

No problem. According to this site:
http://www.gsmarena.com/htc_droid_incredible_2-3938.php
the Inc2 supports gsm 2100 which I believe is one of the same frequencies of T-Mobiles 3g network. I can't help you any further since dealing with frequencies and other networks isn't something I know of.

Can it be used with att? Like say with the straight talk e71 sim card ?

OP, how do you make it work? Have you verified with Tmobile sim card? I unlocked hinc2, but it shows "no service" with tmobile sim under GSM.

yep it can be used with any sim carrier. just do not know if it will support their 3g data because the adr6350 opperates on frequency 2100 and not also the 1700

you have to set up a new apn for t mobile. you have to go into settings-wireless and networks- make sure you have it set to gsm not cdma to make it work. - go to mobile networks- GSM/UMTS options. - acces point names and if its blank press the menu button on the phone and select new apn.
this is what you need to write in it.
Name: T-mobile or whatever you want
APN: epc.tmobile.com

and this shuld enable your tmobile on your htcInc2
hit the thanx button if this helped

I've been trying like crazy to get mine switched over from Verizon to T-mobile and was soo happy to find this!! I'm having a problem finding my apn numbers and that data listed. When ever I try to switch mine to GSM or Global it say there is no SIM card installed and automatically switches back to CDMA. How can I stop this or how can I change the info another way. I have it rooted already and I'm running the ClockworkMod. The phone doesn't have service but I have activated the Tmobile card already, just can't get the bloody thing to work!
Any help you can give you'd be extremely appreciated.

Did you get this as a pre-owned phone from someone else? Is it Sim unlocked - do you know?
If the answer is yes, when you go into APN - you need to create the above and SAVE it first. What ROM are you running?
I've uploaded 2 *.jpg images - not sure if it's showing up correctly? Can you reference & compare the screens and share what yours are?

No this was my phone to begin with. I just got tired of Verizons BS and switched to the Walmart Family mobile that is a third the price, but I couldn't afford a new unlocked phone.
I did manage to unlock the Sim, called Global Support from Verizon and they gave me the code no questions asked.
After I unlocked it and got it to recognize the Sim card I found the APN section and got all that setup like it was shown on here now it's working perfectly!
I'm running the stock ROM. I would like to upgrade to CM7 or something like that but I don't know how to upgrade my Kernal to accept the upgrade so I get stuck at the White HTC boot screen whenever I flash a new ROM. So I just defaulted back to 2.3.4 til I can figure it out.

Great, glad to hear that you got it working on Walmart's T-Mo family plan now, it is "slow" on mobile data but just as good when you are on WiFi. We retired our 2 DI2 last month and ditched Big Red, I hear ya - we saved 50% each month, more than enough to pay for two Nexus 5.
If yours is rooted/bootloader unlocked with CWM, you don't need to do anything with the stock kernel - just leave it alone, find the custom rom's zip file that you want - copy to mSD card, boot into recovery - do a full wipe, flash & reboot, then setup as usual & restore your apps. The stock VZW rom has all the bloatware that are useless, especially on other carriers - use Andy Bone's stocked Rom instead, or SkyRaider's Zeus or TSM Sense, all 3 of them works 99.89999% in GSM (using 2 of them now) - read the FAQ / Sticky first, as it is detailed & explained it all with how to's. I have those roms in offline storage - PM me if you cannot find a working public links to download them.
Prices for brand new 4G LTE smartphones are mad crazy, I understand - VZW wanted about $300 each to upgrade + fees + ETF & 24 months contract, if you shop around when ready on eBay, you can find some pre-owned ones that are solid with custom Rom, and reliable with reasonable prices on the 3G HSPA side, i.e. saw pre-owned Motorola Atrix 4G with 4" screen in good conditions for about $70 - in exchange, you get much faster 3G/HSPA+ speed with mobile data (if you need it on the go)
Have a safe & happy holiday.

Skyraider is probably one of the best sense roms on gingerbread with a few tweaks to it. Thing with unlocking the sim on this phone to work on a different network u will eventually start to have issues since it was designed for only verizon cdma and global gsm only. A lot of the gsm is still in the work. When unlocking any phone to work on a different network ur mostly always gonna have an issue with 3G bec gsm is on a totally different band and unless the phone itself was designed specificially for gsm itll be an issue ull more than likely have. An apn change might fix it but not a lot of roms have the apn settings unless its more the line Cyanogenmod. There is an apn settings shortcut in the playstore u can use to set it. Me personally i wouldve stuck with Verizon because the majority of the worlds population is cdma service towers and tmobile has less coverage then sprint or at&t but too each his own. Good luck and hope the apn change helps gain u 3G

Connection failed due to incorrect APN setting

I took the SIM card from my Sprint global phone and put it inside an unlocked GSM HTC One X for use in Mexico. As Sprint has roaming agreements with Telcel (GSM), and the phone is unlocked, this should work. I'm able to make and receive calls on the phone, but I can't get data to work!
The error I get is:
"Connection failed due to incorrect APN setting"
I checked the APN in mobile settings, and this is what I have set:
Name: Sprint World
APN: cinet.spcs
MCC: 316
MNC: 010
Everything else is blank or set to defaults.
Anyone have any suggestions? For some reason, whenever I try to change the MCC or MNC and click "save" the APN disappears and I have to restore defaults for it to re-appear.
Thanks in advance for your help. Really want to get data to work on this phone!

I can't advise on specific settings, but you might benefit from just calling sprint? Make sure the settings don't actually change to something different when roaming? Or maybe they only have an agreement for voice calls etc but not data..

Since Sprint isn't a GSM carrier you're probably one of the less than 10% of their customers with a GSM SIM. It's a long shot than anyone here would have experience using data internationally on a Sprint SIM.

[Q] Phone won't roam-settings are missing

Hello everyone,
I have a new AT&T plan with five lines, all using Samsung Galaxy S3s, all having the same problem. My 14 day grace period to cancel is almost up and I'm at my wits end searching for an answer. The phones are not rooted as I do not understand most of this technology; however I'm smart enough to know that this is a problem beyond rebooting the phone or resetting the SIM card, as every forum out there is telling people to do. Calling tech support (please don't make me) is a LAST resort for any device I own.
In the town where I work and shop I have no signal at all from AT&T. No voice, text, or data. AT&T coverage map shows "good" coverage in this town. Every so often I do get a weak AT&T signal but only for a few seconds. I do however pick up a very strong signal from a T-Mobile tower. I know that AT&T and T-Mobile both use GSM and should be compatible for roaming purposes, but the phone does not roam; it just shows a strong signal that I cannot connect to. Also, it switches back and forth between these two towers. I posted screen shots taken one minute apart.
In my phone's "Mobile Networks" settings there is no option to chose a network. There are only four options on that page: Mobile Data (checked), Data Roaming (not checked), APN, and Network Operators. I have tried adding a new APN but that did not work. The Network Operators tab says "Default Setup" and I cannot change it. I understand this is an issue with AT&T - they deliberately remove these settings.
I have gone through all the settings in Service Mode using *#197328640# looking for a way to enable the missing settings. I have already used the Service Mode to disable LTE (another setting AT&T likes to deprive us of) but that was not the problem so I put that back on automatic. I have also checked and unchecked every imaginable combo of settings such as wifi, data, airplane mode, etc.
I think the problem is either that the T-Mobile tower is interfering with what *should* be a good AT&T signal, or that the fact that I am "connected" to AT&T (albeit with no bars) is preventing me from roaming. I'd like to know if there is a way to disconnect from AT&T to test that theory. Also, I'd like to know if there is something I can do from Service Mode to enable the missing settings so I can set up roaming.
Thanks so much for any suggestions or help.

Just the default one called "ATT Phone".
I tried a Cingular APN in order to get a better connection to the AT&T tower, but it didn't work and I removed it. I found the T-Mobile APN info and was planning to try that next time I'm in town if I don't find some other solution first.

Is it the wap.cingular or pta one? You have to reboot after changing apn's but I'm sure you already knew that

I used the wap.cingular one and did reboot. Do you think this is an APN issue? I'm kind of at a dead end unless I find where to enable those mobile network settings. Thanks for your responses.

Unfortunately, it didn't work. I also tried to use a T-Mobile one and the phone wouldn't even let me save it.
I broke down and called AT&T tech support to find out where the roaming settings are in the phone... of course they didn't tell me, but they did tell me they don't have a roaming partnership with T-Mobile in my area. Therefore I'm out of luck and will be cancelling my contract.

[Q] Trying to use T-mobile SIM on Verizon N3. No Signal. Help!

Hey guys I recently acquired a Samsung Galaxy Note 3 from a friend who was on the verizon network. I, however, use tmobile but according to youtube videos and online forums Verizon's Note 3 works both GSM/CDMA without the use of a root. Well, once I acquired the phone from my friend, I was able to use it by tutorials on youtube. It worked for 2 days but now I cant use it because it says No Signal. I did steps 3 times and no luck, including a reset. Any input? Please help!

Have you checked to see if the phone was not blocked?

Yeah the phone had a bad esn but I was able to get it uplifted from the original owner. It is now ready to activate yet it can't find service. If I pop in a non active Verizon sim, You can see that there's a signal. But with a t mobile sim there's nothing. I called t mobile and they can't help me cause it isn't "their" device.
Would a root be possible? I never done that before. What are the steps to unlock the device? I'm am willing to PayPal someone with the correct answer!!!! I just want this phone to work.

Yes you will need root!
It may be as simple as editing the APN and the BuildProp to get you up & running!
I have a Note 3 900V it does work on ATT & Tmobile but to get the most out of it it will need to be on Edge, I will not get 4Glte only 4G...
Hope that helps

I had a rooted, unlocked Note 3 from Sprint (CDMA), and while the Note does support both CDMA/GSM, it is only internationally that it works on GSM. Here in the states, you are SOL if you have a Verizon or Sprint version. They WILL NOT ever work on T-Mobile/ATT. Sorry, just trying to save you the frustration that I went through. Sell the one you have, or trade it in with T-Mo's JUMP. as long as it boots, and is in good condition, they will give you $140-$200 towards a shiny new GSM Note 3. Good luck!:good:

Not that complicated.

You guys are making it harder than it is. Just change the network mode from CDMS to GSM and the T-mobile SIM will work. No need to root, unlock or anything. Even if bad esn, it will still work on GSM networks. Currently the CDMA and GSM database is not shared. Hit thanks if it works.

I did do that. I did it 20 even with a hard reset, reboot, installation of new firmware. Still got nothing.

Did you check putting the T-mobile SIM in another phone and see if it is working? It might be that since the phone was blocked on verizon, the SIM got blocked. Normally what you have to do is put the SIM in another clean phone (the SIM won't work still), call T-mobile and ask to ublock the SIM from another phone, the customer care would ublock and ask you to reboot and it would work again. If asked you can say you bought the phone on craigslist(CL) and then the seller reported it lost and so it got blocked.
I have been burnt twice with Note 3 and once GS 4 (total 3 times) from CL that now I have stopped buying from CL or swappa. There is not much you can do for people who run these scams even if you have all the proof, it wont worth the hassle. I went to cops, showed then the ad the guy put, gave the ATM receipt, photos of the bills I have handed over, the texts exchanged, asked for the video footage from HEB but nothing happened. So lessons learnt no more phones on CL.

Hard to believe you did this three times. I wouldn't have tried it even once after hearing about how people were getting scammed with no recourse, let alone more than once.

you need to check your apn settings...
look for a software that will let you change it. I don't remember the name... from the play store..
my cousin had the Verizon note 2, we first rooted, we unlocked the sim with an app, and used a software to change the apn settings and it worked with my tmobile sim..
so you can make it work from Verizon..
sprint on the other hand, locks there phones for only international use, I do know that.
if the phone is Verizon, even if its blocked the imei, that should not even bother on another network,,

Galaxy S4 4.4.2 NB4 won't send MMS or receive em =/

I got this phone for my dad, as he had this old crappy phone for years and overpaid for his cell bill every month for minute plan lol i know.
So i got him this Galaxy s4-m919 model to find out that it was upgraded as part of a plan, then the person claimed it they lost it to sell it to another person, and ofc they wouldn't refund me.
So i took another path and came on here to get help, ofc it was a T-mobile phone, so I guess i'm blacklisted on t-mobile networks, but i flashed to 4.3 modem, did sim unlock, then flashed back to 4.2.2.
Put in my new Att sim card, and service has worked ever since, the lame part is now he wants to use MMS, and it keeps on failing to send/receive, when he recieve a mms from someone, it comes up as a huge ass url(you have to click it to see the picture in the browser or w.e, but never ever loads rofl, idk y.)
He doesn't use any apps, he just uses it for calling, internet at times, navigation, wants to use MMS, takes pictures/video, etc. But MMS doesn't work, I ever called the H2O to help me, and they said that i needed to change my "Message Center #" for it to work, seriously? My other phone has "+12063130004", and my dad's is "+13123149810", i think H2O rep wanted me to change it to the # my other phone has which is the first number i listed. Is this really the care? If so, how can I change it? =/

First thing to check, in my opinion, is to see if all the APN options are set correctly. Settings \ Mobile Network \ <more> APN Settings will usually get you there. The ATT APN settings can be found here but you may need to search around if H2O requires different ones. I'm on standard ATT and the settings at that link work for me, with my M919 phone.
Good luck!

I also saw somewhere that you can hook up your phone to the computer and change the Message Center # using Root Explorer(just re-read the post on xda about this and u have to have it rooted =/), then 'SilverEdit' to edit the xml to enter the message center number?( also heard it wasn't permanent either, if u turned it off, or battery died or w.e. it would revert to the previous #, not sure tho) Not sure what to do here. The internet works fine, but H2O rep says i need to change my Message center number to a different one for mms to work. Also tried changing default msging app to hangouts and sending a mms, and it came up with " mobile plan blocks MMS." I also put his sim card into my working phone, and ofc the message center # was the same when i switched it over to my phone and ofc it won't send, says "mms not supported by network, service response error"

Anyone?

Can anyone help me with "Message Center"? My MMS doesn't work, can't send or receive(when i receive an mms, it comes as a big ass url something like "viewmymessage.com/webgui/bla bla/ bla bla/ and so on/", can't open the link on the phone.

If you have AT&T service on a t-mobile phone it needs to be unlocked. He is using it to call people, so I guess it is. You should try flashing an AT&T modem.
Before that, try making your APN type: IPv4 or IPv6. And MM message proxy:0

I'l try that, just put in my H2O settings: APN type: IPv4 or IPv6. And MM message proxy:0; Can't try atm, as for some reason his data went down to 0, even tho he wasn't even using internet for anything on his phone...which was weird. The way I unlocked this phone was flashing the 4.2.2. modem, then went thru "service mode" and did step by step. If the Apn settings you gave, wouldn't work, would flashing the att modem 100% work(got link for the modem, cba to find it atm, last time if flashed it, i used odin)? I'm on 4.4.2 Android version, Baseband: m919uvufnb4.

You're with AT&T on a Tmobile phone right? You should still need to have an AT&T modem. In the slot where it says "APN type", put it as IPv4 and the slot below "APN type", put it as IPv4, also. But non of that is worth trying if you are using AT&T service. You need AT&T modem and APN settings.
Edit: I was watching a movie and read you comment wrong lol. Yes you need to flash AT&T modem and APN

No problem, I was just wondering, is it safe to use other carriers modem onto T-mobiles phone, yet using At&ts modem(diff carrier), some people said it could screw up your IMEI or w.e rofl. I found the modems for i335 which is Att here: http://forum.xda-developers.com/showthread.php?t=2496517

Ahh okay, so I can just flash ATT NI1 KK modem(9/18/14) modem thru odin and i'm good? ;p
Off-topic, if you flash to att modem and you already unlocked your phone or w.e., nothing gets effected, once unlocked, stays unlocked eh?

Actually, be careful with this. The modem (which is two parts) has to be paired with the phone model. For example, an M919 can't use the modem from an I337. The Modem runs the radio hardware, which varies by phone. ATT & T-Mo variants have different antennae bands supported, so need somewhat different radios. I'm not sure if trying a different radio will brick anything, but numerous threads have said it doesn't work. The modem consists of the modem.bin (the "GSM Modem") which can be flashed at will, and the non-hlos.bin ("LTE Modem")which needs to be paired with the phone bootloader, or else chaos ensues.
You DO need the right APN settings. Unfortunately, I have no experience with the message center thing... can't help there.

Your phone will still be unlocked regardless. Try to change the APN setting to AT&T first. Like Frankenscript said, both phones have different radios so changing the modem might not work.

I seen people say it works and others say it didn't. Nothing about bricking the phone tho but I do understand what you are saying.

I tried ATT settings, didnt work. I put on H20 settings that were on the site, didn't work. Tried my bros H2O settings that he got from chat rep on their site, then 4G started working, but I keep getting "Mms failed, server error" or w.e. keeps failing, put the H2O internet settings(on), and mms settings. Not sure if his phone is missing something or because his phone is blocked on tmobile's networks, his using H2O meaning his on ATT's network.(i bought him a cheap 1$ mirco-sim, off ebay) Not sure if that plays any role, the calls are good, dats works now, etc, just mms wouldn't work. Suggestions? Some1 on H2Os rep side said it could be the "message center #", that's y it can't be sent or receive or w.e.(His is atts message center #, and its greyed out"

Anyone know how to fix mms problem?(cant receive or send atm, tried a lot of things). Mms keep failing, server error, not supported by network or w.e., lost on wut else to do.

Anyone?

This is the root of your problem, buying stuff from other people, it's probably stolen.
Throw it away and go buy a new phone from Att and this issue will go away.
Somethings fishy here.

Cell 4 sale store was selling it, not just a random person. I guess they probably either do it themselves ir buy it from ppl who do it.(upgrade their phone to gs4 or w.e. then claim it lost or stolen, thus keeping their old one and selling the new one) I think they probably flashed it to work for internation, but idk, might've been rooted before 4.4.2, since ota got installed, means root is gone. Anyway to fix the problem instead of just replying with a negative reply? I want to use the phone, calling etc works fine everywhere, 4g is a bit in some places, mms doesnt work at all, one rep at h2o said it might be cuz of message center number, he wanted me to change it to a diff one and see if it solves it or not, but my message center is greyed out.

Apparently there is something wrong with it, at least you should be able to get it replaced for one that works. It could be a build.prop issue. Just guessing.
Pp. Good luck.

Still looking for a solution, anything I could try, to fix Mms to work again?(cant send or receive as it says "server error", failed mms, etc)
