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.

I have a serious problem with my Wizard. I have the phone for months but the problem came out 2 weeks ago. The problem that It automatically disconnects from network. I mean I turn my phone on, I type the PIN then after hours or minutes (I don't really know) it disconnects from the network, so nobody can call me and I don't get any SMS. Also a problem that I can't see anything of that issue. I mean it still shows me that I'm on network, it displays my operator name (Pannon 3G) and I have high radio signal. There are 2 solutions. I need to restart it or after I call somebody I get all the sms I should get while I was unavailable and everybody can call me. Then the problem occurs again in minutes or hours. I tried to hard reset my phone but resetting didn't slove the problem. What should I do?
Edit:
Can an installed software cause this?
I'll try to hard reset my phone again and I'll install just the softwares I really need (3: msn, music player, video player). Then we'll see, but I'm still waiting for any ideas.
I also noticed that it works perfectly at the weekends (on saturday and sunday). But On the other 5 days the same problem occurs...
Ok, so here is which I found. I had that icon on my status bar since I hard-resetted my phone.

(A connection inactive icon) And about 4 days ago (I didn't changed any settings or install anything) it changed to that:
(An EDGE network is available) And now my phone is still working fine (as a phone :/) from that time changed. So how it changed automatically and what is the connection with EDGE network?
Major pain in the ass this,

This is me just as I have unlocked the phone, you can see full signal but its grey and not blue, also on Edge when it should be on H
This is the O2 APN I am on
This shows mobile data is turned on
This shows it finally connected to H, it took me 6 minutes for the phone to connect to data as you will see when comparing the first and last photos, to get this to connect it involved me rebooting the phone, selecting a different APN then going back to my own, quite a pain in the rear, and this is fine until you put the phone to sleep and then you've to go through the same process
I can only assume this has something to do with the radio as the sim works fine in my Galaxy S2, and here's another thing, when the signal is grey and not blue if I try to make a phone call I bet a beep and a call failed error.

Radio Version? ROM?
[My new Galaxy S5 does not seem to be getting great signal reception. It's constantly around -100-106 dbm. I downloaded an app that checks it every 1 minute and then produces the results in excel forumat. Other devices in my office (also on verizon) are getting much better reception
I went to the mall, and the Galaxy S5 there was around -80, while mine was -97. Obviously both Verizon. How is this possible, other than a faulty radio in my device?
I remember back in the day you could dial #228, but obviously with 4G you can not do that.
Should I return/exchange my phone?
I should add, if I power off the phone, take out the sim card, then reinsert it. The signal improves to like-84-88 dbm for awhile, then tapers off again to the -100s.
Will SOMEONE chime in their thoughts?
You can see in the circled area, if I do a restart, the signal is better for like 5-10 mins, then drops off again. I even tried to do all of these things in safe mode, same results.

Maybe you should check the signal power when you actually use your phone ( in a call) maybe is a power saving feature. Try to compare with other s5 in the same room. Could be a bad driver for modem. From my experience with Samsung it takes 2 or 3 updates to get all well.

Hello, I bought the AT&T Variant not looking into the Developer Forums and not Knowing AT&T also Locks bootloaders, Coming from Verizon on the GS4 (Rooted/Safetrap/Hyperdrive Rom) i should of known better and did a little more research on the device but it was a quick decision since i was already in the AT&T store and this just dropped that week, i had to have it. Fell in love, compared with the N4.. Eh wasn't that impressive i wanted something no one had and to make my iPhone drones friends envy. So i was gonna activate with AT&T but i remembered that Straight Talk uses the same Towers as AT&T i decided just to buy a kit and run a few tests myself, quickly learning how to get the best APN and doing multiple tests with different APN's i finally hit that sweet spot. and im glad to share my results on how to have a massive power horse at the tip of your fingers for a fraction of that high ugly contract bill from AT&T.

I totally agree with you.
Coming from a Verizon Note 2 and using it on Straight Talk, H+ wasn't doing it for me.
And since it also has a locked bootloader, I kind of killed it with the new root.
I need the phone for work so I took the dive and bought the phone yesterday from AT&T.
Today I find out that it also has a locked bootloader but I'm not going down the root path anymore so no big deal there.
I inserted the 4G LTE Straight Talk Sim card, set up the APN and it's AWESOME. I finally know how it feels to have LTE speeds.
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.
