tmobile htc pro 2 GSM/UMTS Band !!!

hi there
well my problem is that when i choose the band of 850. the phone cant really find my network band......
im from costa rica , and our 3g band is 850.
i used to have htc pro from att and it worked 100%
but now with my tmobile, i really dont know why i cant connect to my 3g network. EVEN that my phone gives me the option to change the BAnd.
T-Mobile's 3G band is 1700/2100MHz. Most of the world is different. If your phone isn't T-Mobile branded, it probably has no way to get on the T-Mobile 3G network.

[Q] 3g problem on frequency incompatibiliy in Brazil?

Hi all,
I bought an HTC One X AT&T recently. On a trip to Spain installed a Vodafone sim card. The voice connection worked perfectly, but I could not use the 3G. The same sim card work worked perfectly in my wife's iPhone 4s. Back to Brazil, I'm trying to use a Oi sim card and have the same problem. I checked with Oi operator and it uses 2100 mhz for its 3G network. In both cases I got an 4G icon (not 3g) on the too bar.
Do I have a real problem with 3G hardware of my phone or I'm missing something? Is there a way to test 3G radio?
Thanks for any help!
You have to manually enter the APN info for the carrier in order to get data and MMS.
Assume you are SIM unlocked, as if you were not voice calling should not work either.
I've used the AT&T One X in Germany a few times and had no issues with HSPA+ data on the 2100 MHz band.

[URGENT HELP] 2G/No signal on my Nexus 5

Hey guys,
So my Nexus 5 stopped working the other day, and I sent it for repairs. It's come back now and I got a new SIM. Airtel 4G here in New Delhi, India. The problem is, it will only show me a 2G connection/no signal at times. I don't know what to do. The SIM works in other phones perfectly well. I've tried going to *#*#4636#*#* and changing to WCDMA only. Doesn't work. What is the alternative solution guys?
The phone was bough in the USA but before it got repaired, 3G worked flawlessly. So at least that should work, if not 4G.
Thanks,
Crazysah
No one has had this problem? Or no one knows a solution?
Hi, Airtel as I see operate in 2G (GSM, EDGE), 3G (HSPA+) and 4G (TD-LTE band 40). But Nexus 5 (USA model) D820 doesn't support TD-LTE (band 40), so for sure you can't connect to 4G. But 2G and 3G should be ok. You can reset network settings and check again.

Yes. 3G should work at least. But it isn't and that's the problem. Before repairing it, it used to work with my mom's Vodafone 3G connection. What's the solution here?
Can you try to restart and after that change to "GSM auto (PRL)" from *#*#4636#*#* menu? Are you tested other device with this SIM in the same location ?

Any idea guys?
