For all Verizon MVNO customers (Page Plus, Straight Talk w/VZW sim, ROK Mobile w/VZW sim, etc)
are you able to get a data connection while you are talking on the phone? I ask this because we are unable to activate "Advanced Calling 1.0"
New CDMA phones do not have two radios(voice/data). The issue exists on both CDMA carriers. I moved from the Evo LTE which had the dedicated LTE radio to allow data during calls. The 5x does not have the hardware to allow data during a standard call and will only be achievable when the carriers implement VoLTE.

I have an HTC TouchPro 2 that I bought from T-Mobile here in the US. While I now have an account with T-Mobile, I was able to get this with no contractual committment. I also happen to have an AT&T Fuze with an account at AT&T. Originally, I wanted to move my cell service to T-Mobile, as I can get the same service for about $30-$40 less per month from T-Mobile than I pay AT&T. However, I have discovered that T-Mobile does not have nearly the data network speed that AT&T does. I can get 3G from T-Mobile, but not nearly as widely as I can with my AT&T phone and service. Consequently, I would like to convert the phone to AT&T. I have unlocked the phone, and upon moving the SIM card from the Fuze to the TP2 I can make AT&T calls with my AT&T number, but moving the SIM card doesn't get me connected to the AT&T data network. I finally figured out how to connect, but I can't get 3G to work.
Does anyone know how to solve this problem?
AT&T and T-Mobile use different 3G frequencies. So your T-Mobile TP2 is not compatible with AT&T 3g frequencies. The best you will get with your AT&T sim in there is EDGE.
Same problem in Oz...
Telstra uses Next-g network - 850Mhz...
Everyone else uses 3G - 900Mhz...
We have the Touchpro 2 Model 7373 (3G) and the 7381 (Next-G)...
Telstra sim in a 7373 variant means edge service but another carrier uses 3G.
Vice Versa in a 7381 model...
Bloody annoying... Should use ALL frequencies, that would be easier, especially as it say 850 - 1800 Mhz on the band page...
Oh, well....
Not exactly what I had hoped to hear. Thanks for the answer. I guess my next step should be to see if there is any hope for T-Mobile to improve their data coverage.
Hello,
I wanted to see if anyone has successfully SIM unlocked a T-Mobile Galaxy Note 3 to Sprint and everything working functionally.
Thank you,
Crap, I just wrote you like a page on this and the app crashed and lost all of it.
In short, it's definitely impossible. The GSM phones do not support any CDMA2000 2.5/3G frequencies which is what the US CDMA carriers use exclusively for voice and SMS.
Even if the T-mobile model supported the necessary frequency bands / CDMA2000 standard, Sprint would never allow it on their network. Sprint and Verizon only allow their own carrier branded phones on their networks. They each have a database of IMEIs for every phone they've ever sold. If your phone isn't on the list, they won't allow it on their network PERIOD. It doesn't matter if it's fully hardware compatible. They want to control every aspect of your mobile experience to extort more money out of you.
Looking for a clarification here before I make the jump to a dual sim phone. Located in the US.
My goal is to combine 2 services into one phone. I have a primary Verizon MVNO service that I use for Calls, MMS and Data. I want to add a second SIM, preferably also a Verizon MVNO, for Calls/Text.
I have seen some comments indicating that you can't use 2 CDMA SIMs at the same time.
If that is the case, the only option for the second SIM would be a GSM service, correct? If that is the only option, can the second SIM can only be used for Calls and Text? How about MMS? I assume NO for MMS on the second SIM.
I was considering this phone because it seems that both SIM slots support CDMA carriers. But, if you can only use one CDMA SIM, and am forced to go with GSM for the second SIM, I will reconsider the cheaper ZTE Axon 7 option.
MMS doesn't work on this phone.
When I spoke with Verizon about this, they stated it was due to the phone being "unknown" on their network, so MMS limitations are enabled as they can't identify the phone. This is because Xiaomi doesn't register devices with all carriers.
Personally, I would keep looking. SMS, calling and Data have been working fine.
Hello all!
I have an LG G7 from India, model G710EAW. I moved to the US from Canada and the phone isn't entertaining T-Mobile or ATT SIM cards. When I insert them, service works for a little bit and then immediately switches to "Emergency calls only". T-Mobile's website says my phone IMEI is compatible with its service.
The strange thing is that the phone has two SIMs from Canada roaming - one on the T-Mobile network and another on ATT. No issues whatsoever. And when I check the bands in Engineering Mode, I can see one roaming SIM running on LTE Band-4 on T-Mobile. The other roaming SIM is switching between LTE Band-2 and LTE Band-5 on ATT.
T-Mobile uses bands 2,4,5 mainly, and ATT uses 2,4,5 among other bands.This leads me to believe it's some kind of a network restriction preventing my phone from latching onto these networks directly.
I've made tons of calls to T-Mobile and ATT so I'm no longer interested in pursuing them with this.
I'm wondering if cross-flashing a different firmware might help fix this issue. I remember reading on this subreddit that the Google FI firmware may work for T-Mobile bands. I'm not sure I understood that correctly.
Can someone confirm if that's possible? Does this make sense? I'm hesitant to buy a new replacement phone when my G7 works so well.
Thanks!
After having the switch to T-Mobile due to the eSim restrictions I've given up on getting Verizon or AT&T on the esim so I asked T-Mobile why I couldn't roam off AT&T well she proceeded to tell me that they didn't have jurisdiction or whatever to connect to the towers in Vermont where I am but she told me how to make it so I can manually select what towers I'm connected to so I've been roaming on T-Mobile with AT&T for the last hour I have 4G LTE and I have all the service I've been looking for...
I don't know how much Roman data I have but I at least know I can now connect to AT&T and have service I can also now do roaming with Verizon just nice to know that I can actually select the carrier and have working roaming
