Question Ultimate data fix for esim - Samsung Galaxy Z Fold 4

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

Unlocked Issues

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.

[Q] force roam to AT&T tower

I live in Puerto Rico and AT&T has the best coverage were i reside. I can actually see the AT&T tower but my Evo 4g is still picking up a weak sprint signal 1 bar. what can i do to force it to roam on AT&T network. I know about roam control but don't want to be on 1x data.. thanks

Sprint can't roam on at&t. at&t is gsm, sprint is cdma. 2 different networks.
Don't think its possible. ATT is a gsm network. Our phones run on cdma.

No. You're doing the equivalent of trying to play a VHS in a DVD player. It ain't gunna happen.
so in Puerto Rico AT&T is using CDMA so can some one help me out
(AT&T buys Centennial phone Company)
AT&T will continue to operate Centennial's CDMA networks in Puerto Rico and the U.S. Virgin Islands, rather than immediately move all customers to GSM/UMTS. In July 18, 2010 AT&T absorbed Centennial in the Caribbean
Centennial also operates CDMA networks in Puerto Rico and the U.S. Virgin Islands.

Still won't work. Sprint would have to have a contract with AT&T/Centennial to allow roaming... And if you're not already roaming, then it's not going to happen.[/thread]
[Q] AT&T using CDMA in Puerto Rico , force roam
I live in Puerto Rico my phone gets a weak signal from sprint 1 bar but there is a AT&T tower that i can right by my house (2 blocks away) when my phone roams it gets a full bars with 3g service but that does not happen much cause it also gets a weak signal from sprint how can i force roam to AT&T with the prl not the "Roam Control" cause of 1x data issue thanks

i roam every now and then with full bars and 3g at high speeds
You could try the roam control app, force roam your phone to get a better signal, but your data speed will suck. Its a paid app.
Just taking a guess, you could be roaming to Claro, the old verizon here in Puerto Rico. Oh and another question i am getting some bad speeds on 3G in Mayaguez...about 200-500 kbs in dwnload and 100-500 upload
Look, I said it before, and I'll say it again:
Unless Sprint has a roaming contract with the local carrier (AT&T/Centennial) you will not be able to roam on them. At all. Ever.
And if you do roam on someone other than Verizon, odds are you're going to hit roaming fees.
Rather than asking us, why don't you call Sprint, and ask them what their roaming policies are in your area, and on who's towers you can/will roam without getting fees?

I think you are right, we used to have Verizon here and Claro bought all the towers and stuff they had. I think he is roaming with Claro that is exactly the same infrastructure Verizon had here from what i belive. My best guess is he is roaming on Claro
well...i live in Carolina, PR and i just got Evo on Sprint yesterday because Tmo has no service in my home... here the evo is roaming data and voice from at&t/centennial because i dial 611 and it was at&t/centennial customer service line... i have '3g' but only at 100kbps or less!

Can I force roaming on tmobile network with an at&t sim card?

Hi everyone,
I recently obtained an AT&T sim card and installed it into my unlocked and rooted tmo g2. I was under the assumption that I would be able to at least get 3g on the AT&T network with my phone, but did not realize that the g2 does not support the frequency bands for at&t 3g. I currently only get 2g/edge, data is slow and calls are sketchy.I have all the apn's setup correctly, I know I do. The phone simply does not support the frequency for 3g.
I was wondering if I can force my phone to always roam on the tmobile network somehow so that I can obtain 3g or even by some stroke of luck 4g. I have national roaming so there is no charge.
Is This Possible???
Somebody please help me figure this out or tell me why it will not work.
XDA is a genius pool, somebody out there knows...
Thank you in advance

You can use AT&T's network with a phone that has an unlocked sim slot, but AT&T's 3G band (same band Canada Bell 3G is on) is different from T-Mobile's, as a result you won't be able to use 3G on AT&T's network.
The same is true if you bought an international Desire-Z and tried to use a T-Mobile Sim, no 3G speeds on T-Mobile, but 3G with an international GSM/HSPA carrier.
PS: The G2/DZ does not support 4G, the only time you ever seen 4G in the indicator is when the phone is on HSPA mode (kind of in between 3G and true 4G speeds).
In a nutshell, a T-Mobile G2 will ONLY be able to get 3G and faster on T-Mobile's Network.
----- The above mainly for people coming in wondering the difference ----
In regards to force roaming with T-Mobile's network, as far as I am aware the two have a limited pairing arrangement, with a AT&T Sim, you would get minimum edge speeds with T-Mobile. (ie: why would a competitor give you more than just basic service). ie: you're not a T-Mobile Subscriber, as such you'll only get Edge (if any data at all) when roaming outside of AT&T's coverage.

[Q] Not getting 3G/4G

I recently changed services from AT&T to T-Mobile but kept my same number and phone. I rooted my phone as well installed Cyanogenmod 10 but now I am only getting edge network and I reported to T-Mobile and they could not help me since they did not know how to repair it and told me I am suppose to be on 3G/4G network since my area has perfect coverage for 3G/4G. The phone is unlocked to use T-Mobile SIM card.
My mobile network settings is set for
Network Mode: GSM/WCDMA preferred
APNs: T-Mobile US
Data enabled
Data Roaming
National Data Roaming
Is there something I missed to do?
try change
Network Mode to LTE/GSM/WCDMA

I already tried that and so far it still hasn't changed into 3G/4G.

You may be in an area not covered by T-Mobile for UMTS/HSPA/HSPA+ service on bands 850/1900 MHz.
T-Mobile usually has its 3G/4G service on 1700 MHz AWS frequencies. The SGH-i747 has an antenna for the LTE service on 1700 MHz, and it is not used for HSPA/HSPA+. Currently, T-Mobile is refarming its 1900 MHz spectrum to run HSPA/HSPA+; you can use this user-generated map to see the refarming progression.

[Q] Will a phone blocked on T-Mobile work on T-Mobile MVNOs?

A few months ago I bought a T-Mobile Note 3 on Craigslist, unlocked it, and started using Net10 (a prepaid MVNO carrier on AT&T's network).
Today, I decided to look up the IMEI of this phone for no reason at all, and saw that it was blocked on T-Mobile. T-Mobile's website said it was reported lost. However, it works on AT&T networks.
So my question is, even though it's blocked on T-Mobile, will this phone work on MVNOs using T-Mobile's network? For example, Solavei, Simple Mobile, or even Net10 (they have a T-Mobile option too).
Most likely no. It will just be a matter of time that the phone will be on the data base and the phone will be blocked. I believe all US carrier share one blacklist database.
It will eventually get black listed call tmobile and pitch a fit I did and they removed the imei from their blacklist the person never paid off the phone
