[Completed] Verizon S4 to Tmobile - problems - XDA Assist

I have a Verizon S4 and switched service to T-Mobile. The phone works for calling but rarely works for texting. Messages fail to send. Data is also not working well. As per advice of Tmobile tech support, I changed the APN settings to work on their network. This did not fix my problem.
Do I need to flash the ROM? Can someone point me in the right direction?
Any help would be appreciated!

[Q] How do I add APNs on Verizon Galaxy S3 running 4.1.1?

I have a Verizon Galaxy S3 (SCH-I535) running Android 4.1.1. I was told by Verizon prior to moving to England that, with this version of Android which unlocked the "world phone" capabilities (GSM), that I would be able to use my phone abroad with a new sim on a local network.
Fast forward a few weeks, and I am in England with an Orange sim in my phone. I have no problems with voice, but I cannot access any data services (I have no trouble receiving texts, but cannot send them - I think this is a problem with the sim though). After searching around the internet for a while, it seems that the solution to my problem would be to add the Orange APN settings to my phone.
HOWEVER, Verizon's version of 4.1.1 does not allow you to edit APN settings! When you go to the APN menu, there is nothing displayed and the only settings option is to Reset to Default.
The closest thing I've found to a solution is here, but it's a bit out of date as the method isn't for 4.1.1. I'm a bit wary of rooting my phone and installing a rom, as I've never done anything like that before.
Does anyone have any experience with this sort of thing that might be able to offer a solution? I would be willing to root my phone if necessary, but I'd need to be directed to a pretty explicit noob guide for doing that :silly:
Thanks!
Getting root is easy with the toolkit linked. Should you have any questions you can read the thread or search galaxy s3 toolkit on YouTube. Just keep in mind some videos are outdated and that you have a Verizon cdma galaxy S3 running 4.1.1.

Search this same thread and the APN fixes are here. There is also an APN fix in Note 2 forum that should work. Once you change APN should be good to go with Orange. Say hi to my Uncle in Birmingham. He on Orange also. Cheers. :laugh:
What ended up being your solution?
I'm going to Italy tomorrow with a Verizon S3 and APN settings are locked. The phone is rooted and I would love to be able to use a local SIM on data!
Thanks in advance.

No solution yet. I'm going to look at the link above when I can get some time to sit down and focus on it. Hopefully it fixes it.
BTW, although it's billed as a CDMA phone, it is able to operate on GSM as well. That's the whole "world phone" thing that Verizon has been talking about.

I understand it's a world phone, but I wanted to drop that in because I wasn't sure if the Toolkit states "CDMA" under the device selection screen. I know the Galaxy Nexus or Razr Toolkit specifically stated CDMA. I just didn't want you to accidentally pick the wrong one. After looking at screen shots of the Toolkit you shouldn't have a problem it doesn't mention CDMA only Verizon is stated.
Unable to add APN.

Hey there,
Sorry for going there, but I have not been able to find a fix for adding in the APN on a Verizon Samsung Galaxy S III. I have it on Cincinnati Bell at the moment, and have it rooted. I have voice and text, but not data. I have used the APN Manager Pro to see the APN that I need to use, but for some reason it will not use it or be able to edit it? Any thoughts?

Yes.
Get titanium backup pro and make apn mgr pro a system app.
You should be good after that.
This is confirmed working on Vodafone Italy and ill post results from China and hk in about a month
And please spread the word on this.
Spiting Verizon is my new favorite hobby.
I have a very similar problem. I have a Samsung S3, not rooted, but unlocked from Verizon. I have been in Kandahar for a month or so. My SGS3 with a local provider will make and receive calls great when coverage is there. My problem is, I can only seem to text local here not back to the US, or get email and no Google Talk. I went to the shop where I got my card here, they told me that Verizon needed to unlock my phone. I know it is unlocked but I made the call home, Verizon told me what I already knew. I went back into the store, once again, next they said Verizon needed to unlock my APN? I called again, finally I got a response from Verizon saying that Samsung needs to release the patch so Verizon can unlock it. If anyone knows of such a APN patch I would greatly appreciate it. My lap top screen got cracked during a patrol so doing all of this and email is quite the B!tch! I have always had success with this forum and hope it will continue. Once I send my lap top back home to be warrantied, I will not have any way of getting the usual business done for at least a month. I'm trying to hold off on the lap top until I can get my phone fully functional. I do not have internet connection on my phone, just my computer, I guess that is the APN, that is still locked. I could do all of this if I had WiFi, but it is not allowed here by the company that provides internet. They do have WiFi in some areas, but it is always bogged down with everyone else trying to use it. Also, I am not too sure if I want to attempt to do a root, the internet service here is very slow. Thanks for your help. Please remember, I am atleast 8 1/2 hours ahead of you, so response time will be delayed.

[Completed] Needing help finding a US APN for a Doogee phone

I'm new to the forums. For some time now I have used Straight Talk for a carrier using AT&T and T-Mobile phones with sim cards and have always setup my and others APN's without any issues. About a year ago I purchased a Doogee Voyager DG300, which from my understanding is a clone phone, from China. These phones have no carriers and come unlocked. The Voyager has version 4.2 on it and it worked great, until a blemish in center of the screen, almost like a ripple appeared from spending to much time in my front pocket. I recently upgraded to the Doogee Hitman DG850, it has version 4.4 0n it. Very nice phone. I can send and receive calls as well as send and receive texts, including MMS, without any issues. My issue is I can not get data on this phone beyond 2G. I've tried every APN variation possible including switching sim cards. I have checked the frequencies in my area versus the specs on the phone and every thing looks right. I have spent several hours with Straight Talk reps as well as an hour or so with a Google rep trying to resolve the issue. The phone works great on wifi, but the data responds like dialup. The Google rep advised me that even tho Doogee is not on the list of manufacturers for certified Android OS but checking the version I'm using he advised me it is a proper build version of KitKat. Can anyone help me?

[Completed] Phone connection help please

I bought a galaxy note 3 t-mobile that is unlocked from a friend. I have cricket as the service provider and I do have 4g lte only ever once in awhile it will connect to it though but most of the time it's on "e" about 98% of the time. I Google the cricket apn setting and put those in to see if it would change but still nothing happens still the same thing. Would anyone happen to know apn settings or something I can try? I've even tried *#2263# and changing those setting but still nothing. Any ideas?

Hello, and welcome to XDA!
Seems like the old CDMA vs. GSM compatibility issue. Even CDMA phones can have (what looks like) SIM slots, except CDMA providers like Sprint use different frequencies than GSM providers like AT&T. The phones as a result, cannot be guaranteed to have both sets of frequencies and technologies.
Please try this thread:
> Sprint Samsung Galaxy S 5 > Sprint Galaxy S 5 Q&A, Help & Troubleshooting > [Q] sprint sm-g900p can not work straight talk
It may be the case that your post will just be a "+1", as there does not seem to be any solution (please note, you will need an XDA account to post there).
Hope this helps.

Help with US Cellular S7 on Cricket Wireless

I recently bought a Galaxy s7 from somebody that had it on US Cellular. At first I though it was network locked, however after some research I found out they are unlocked. I popped my SIM in and had to change APN settings and got the sms configuration texts. It says I have 4G LTE plus I'm able to use any apps that require data, able to make calls, and text(somewhat) and it shows the AT&T network logo however it shows no network bars and recently I've noticed I have not been receiving text messages from people if I have not texted them for a while. I'm able to text just fine but after not texting them for like an hour or two if they send a text, I never receive it. I have been sent screenshots proving this. This occurs in areas where there is even good coverage for both in the conversation. I heard I have to flash AT&T firmware but I do not know how to do this. If anyone can help me out it would be greatly appreciated.
