Hello,
I have a huge problem with my Galaxy S5 SM-G900F. I bought it abroad and when I used it for the first time in my country I saw, that there is a problem with 4G/WCDMA connection. When I put my sim card to the phone and set all the preferences in mobile connection menu to "Auto" there is no possibility to call or to recieve calls (even if i saw signal strength meter showing some marks). I can only recieve and making call when I set "only 2G" option and manually select my network. But signal is also very poor.
What I have checked yet:
1. Other sim also doesn't work good.
2. After *#06# i saw my IMEI and it is the same under the battery and on the box (doesn't start from "00") so i think that it is not missed (efs folder).
3. Change firmware with KIES and ODIN for the other version - no changes. Also flash some other "modem" files with Odin with no success in better signal.
4. When im on the free air the signal strength is even at maximum level, but immidiately after going to my house - there is no signal. I saw also, that when im in the city i can connect with 2G network (only), but when im on a village there is no signal at all (even 2G...)
Do you have any ideas what can be wrong? Is this hardware failure? Maybe something with antenna? What should I do before going to gsm service center? Maybe i should change kernel and try some of the custom roms?
Thank you for your help.
regards
Mario
I recently got a voice and text only sim card from Tbaytel (Rogers) to use on my spare phone while working up in Northwest Ontario (DMTS/Knet towers). I sim unlocked it (was a Bell phone) and I am having tons of problems. The phone is rooted and currently running JDCTeam Optimized CM12.1. Firstly, I can not get a signal consistently. If I go into the network settings and move between LTE/3G/2G etc. I will get a signal right away and it will send a text and call out (call outs have problems too I'll address that at the bottom) until I turn the screen off or the phone sleeps by itself. When I turn it on, it just says No Service/RogersTbaytel until I play with the network settings again. And, when it does get a signal after switching the settings around, it's full bars so it's not a tower or area issue.
As for the calling out, it will dial out when I have a signal and my other phone will receive it. However, the S4 phone kind of lags on the dial out and when I pick up the line with my other phone there is no voice transmission from either phone but the call seems to be connected. I also can not seem to end the call with the S4 but I have to end the call with my other phone.
I have tried a few different ROMs, the Google Play Edition 4.2.2 (IIRC) one, CM10.1, CM11 and they all have this same problem.
Any assistance would be greatly appreciated. I have decent knowledge with rooting and such but don't get super technical with me. I should be able to do just about anything with a bit of guidance though.
Thanks.
Just posting this in case somebody has some ideas. I've had a MetroPCS LG Leon LTE (MS345) for over a year without problems, but now it started losing its mobile connection sporadically, for a few minutes or a few hours, as if there was no SIM in the phone.
Symptoms:
The 4G indicator disappears from the notification bar (signal strength indicator shows good signal).
The lock screen says "Searchng..."
Calls fail with the "Emergency Calls Only" message
SMS won't send
I get a "Service Unavailable" error when I choose Settings/Call/Additional Settings
WiFi is unaffected (and WiFi calling seems to work, though it has always been hit or miss)
Things I've already tried:
Checked relevant settings, APNs, etc
Checked the contacts on the SIM socket, all looks good.
Reset Phone to factory defaults
Replaced SIM (MetroPCS did this for free)
New phones are relatively cheap, but I don't have a burning desire to upgrade, so I'm hoping for another option.
I'm having this same problem. I left for an area with no service and came back to an area with service to find that my phone will constantly state Emergency Calls Only and no service. Does anyone have any suggestions?
I'm using Nexus 6p with Jio 4g (India)After update to 7.1 Dev mobile data signal stops frequently (shows LTE with × mark below then shows tower signal only) data connection comes and goes when I'm download apps or videos it stops it's really frustrating
I tried changing APN settings,Network reset,turn on/off airplane mode,factory reset nothing works
Please let me know how to fix these issue
Im just getting an exclamation mark on it any solution
I was playing around with *#*#4636#*#*
Other jio sim has same issue on this phone need help
Please help
Not only 7.1.1 Its the same on 7.0 too. I've tried literally everything. But very frequently i get that Exclamation (!) Mark next to the network icon. If I'm on a call, I'm doomed.
