Hi there, I've noticed that my phone is always in Roaming mode, ie an R is showing in the signal bars icon. It's really not affecting my phone , because I know that I am not roaming, I am connected to my operator (Claro Honduras) . But I wonder what this is all about (maybe because I am not on T-Mobile) , or if there is a way to fix it. Also because of that I have to keep my Data Roaming setting ON, or I won't be able to access my data plan.

I noticed when i am on a phone call, the E or H(aka data tmobile data) turns off while i am in the call and disappears. Then comes back after i end the call. Does anyone else notice this or know how to make it so it stays on even during a call? Also, when wifi is connected the data service turns off?
First off this is normal when your in a 3bars or less 3G/H area. Your phone will switch 2G while on a call if the 3G signal gets low but it won't switch back until the call is ended. Also on 2G/E you can only do one at time, voice or data. T-Mobile's 2G network is stronger than their current 3G network also.
So if your on a call and the H disappears, this means your phone has switch to 2G/E because your 3G/H signal was low. You won't see E on a call since that would be data and 2G can only do one at a time.
If you want to force 3G/H then goto settings, wireless and networks, mobile networks(I believe) and select WCDMA only under network mode. Please note that if you go into a non 3G/H area you will loose complete signal and your phone won't switch to 2g.
and yes wifi disables mobile data.
Good luck.

Okay that makes sense because i only get edge/2g service in my house. Thanks for the response!
My i9505 only connect to GSM network (Only 2g mode) After switching to auto connect (2g and 3g) mode or 3g only mode, phone doesn't register on network. (but showing some of signal bars) emergency calls only. no Data.
When using WCDMA only mode, some time phone showing H sign and connecting to Data network for 1 or 2 min. But again switch to emergency calls only
On 2G only (EDGE) mod phone work perfectly DATA and Voice calls.
Phone has original IMEI and new KNOX boot loader

Is your phone carrier-locked?
Because certain phones can't access 3G/4G if it's carrier-locked.
Where do you live and what service provider do you use? Try changing between service providers to see if you can access 3G/4G with one of those providers.

my phone cannot connect to a 3g networks .. first it find just 2 operators. its Called cellcom and Orange.
anyways the signal is 2g and it cause to my internet to barely work and at the top right of the device i can see a small G letter (from what ive heard it should be H+) i think its because of this 2g mode. when I disable the automatic mode it instantly searching and finding only 2g.
