Help ! 3G not working :(

Hello all,
I am currently using htc tattoo(india) I have 3G services activated on my sim, the problem is after doing all the settings required I am still not able to see 3G in my handset. Is this a problem with the software or the hardware ?
Please advice

Check your baseband version if there is a 13H you are lucky your handset supports 3G, if there is 13G instead like mine you are in the poor club, Welcome

Baseband can't tell you can use 3G or not see on the cover box can tell you GSM only or GSM/WCDMA
My baseband is 13H but my country(TH) cut off 3G hardware to support.
Good luck.

Bad data connection (Galaxy S III I9305)

Hi,
I have started to loose my data connection more frequently in the last days. For some reason
I see see : "Mobile network state: connecting"
After i enable/disable flight more i usually get the data back but its pending allot between Mobile network type: UMTS:3 -> HSPAP:15 -> and sometimes nothing. My signal: strengh is around -79dBm 17 asu (sitting next to a window, third floor if that matters)
Anyone else experiencing data lose ?
Any tips why this happens and what to do?

Checklist Network,
One enter settings for network APN etc .
Two correct modem for network phone and location .
Three correct CSC for network/area
Four problem on original phone providers rom and modem ???
Five might be worth investigation of RIL .

I actually checked my APN. its online.telia.se.
I haven't changed the original Rom so I assume the rest should be correct. I live in Sweden.
Anything in particular I should check,
I'm sort of new in android as well

Unable to establish a Data Connection LTE: ESM - x EMM - 15

Hello, if this is in the wrong section please have a moderator move it, as I am unsure if it should be here or in the Tmobile section.
I have a Sprint Galaxy S7 that I have had SIM unlocked. I have my T-Mobile SIM installed and have data and voice. I am coming from a T-Mobile Note 4 which was working perfectly.
Every now and then(sometimes twice a day) I get loss of signal and sometimes I get this error message that pops up when it happens. usually turning airplane mode on and off will solve it, but sometimes it requires a reboot.
When it happens my signal bar goes blank, I have no data and cannot send or recieve phone calls or Text messages. It is very annoying and I cannot seem to find the correct combination of Mobile Network settings.
I have also noticed slow LTE download speeds and almost non existent upload speeds. Sometimes it says 3G instead of LTE next to the signal.
I live in Chicago and have attached some pics of my settings. If any more pics are needed just let me know. It is so frustrating I am thinking about just trading this phone into tmobile for their version of the phone to avoid all this hassle, but would rather not get ripped off. They say the trade in value is only like $400, but they charge $650 for their GS7, so yea.
Is there a solution to this?

Traded the sprint s7 into tmobile for their version, less hassle. Now I get wifi calling, tethering, and faster lte data without drops.

Update prl..

Hi guys.. I have a freedompop g2 (ls980) I'm not quite sure what they programmed with but some kind of custom rom for their service?
I had this phone working on ringplus but then they booted me/canceled me :angel:
But when I popped this phone on my other ring+ account.. it didn't exactly instantly come up.. I had to program the msn/phone number manually.. and then I got voice service.. but past that.. the 3G/LTE just won't work.. the phone is constantly caught in this mode

}
So I'm not sure what the problem is.. as I see it
it could be
1. software?
2. ringplus?
when I dial the programming code ##775# it crashes.. (hitting activate this device also causes a crash) I also see this problem is for others on ring+ but this phone used to work perfectly before ring+ kicked me off a certain account.
I am rooted have twrp on there.. and have put on this mod and taken it back off.. and I do have it on the wifi.. there is a myth or something that the prl can be programmed by wifi?? but doesn't work in my case.

PRL is built in by different operators, in this case, Its a Sprint service. It won't work if you're not using Sprint I think. 3G and LTE won't work because of different CDMA bands/frequencies.

all I can tell you is I got 1x/cdma working.. I wonder if I can dump my lte sim into another sprint phone and expect it to work?

ahh unresolved.. unresolved..
gonna go to used phone store.. and test my ring+ sim's I get to see if they get data.

How to switch from 4G/3G/2G auto to 3G only or 4G only (Question)

I used to have option in my Note 3 & Zuk Z1 to connect to 3G or 4G only network. it is very useful if you are in low coverage area and your fone continuously connecting to lower technology. Is there any ad-don or way around to get this option ?

very simple !
install 4G Switcher from google play ( only works on samsungs)
open it
select LTE only
its only changes sim1 to lte only.
REMEMBER when you done your job (download) change it again to " LTE / UMTS auto" .
if you choose LTE only , you can't call anyone and nobody can call you !
