I have a strange problem with my s4.
The auto mode doesn't select the 3G/HSPA and instead selects EGDE/GPRS(both networks have good reception).To get 3G/HSPA I have to switch to WCDMA only mode first and then revert back to GSM/WCDMA auto mode.That's the only way to get to 3G/HSDPA signal.
Any ideas?
I tried factory reset, flashed another rom and also disabled fast dormancy but the result is the same. Every mode prefers edge network except wcdma only. My s3 worked with no issues with the same sim in the same places.
Please give me some ideas. It's my phone faulty or is just a software issue?
An update :
I tried a different sim from another operator.
When i set gsm only, it gets E signal.
When i set wcdma only, it gets either H or 3g
When i set wcdma/gsm auto, it finally changes from E to 3g but NEVER gets H.
I have tried everything, flashed different modems, changes CSC, even tried the google edition but nothing works.
Can this be a hardware problem?
Still waiting for any kind of help
At work on Friday I was trying to do anything but work. So, I took the sim out of my work iPhone and put it in my 6P. After booting I noticed it wouldnt connect to 4G/LTE, didn't think much of it. Turned off, the put correct sims back in phones. iPhone boots with LTE connection with work sim, 6P boots with 3G connection with personal sim. Hm.
I tried toggling Airplane mode, data on/off. Tried various 'LTE OnOff' apps. Dialed *#*#4636#*#*, reset APN to default, cleared cache in Storage menu. Wait until I get home, flash latest Android M image (except userdata). No changes after boot, still only connecting to 3G.
Now I've flashed Jan/Feb/March images, no luck on any. Tried Android N, still 3G only...
When I put my personal sim into my Moto X, I have LTE connection and speeds.
Looking for help???

I thought I remember my phone originally being in 'Global' mode
Anyways, my choices are
Global
LTE/CDMA
LTE/GSM/UMTS
I dont have an LTE Only option. I switched to LTE/CDMA, restart. No change. Same when choosing LTE/GSM/UMTS.
Toggle Airplane mode to kick it back to LTE. I've tried a few fixes including changing APN Type but that hasn't fixed it, still happens.
EDIT: Skimmed over the part where you said you tried it, sorry. Try changing the APN type to "default, admin,mms,supl,fota,hipri,dun" in that order.

I tried your APN settings and the settings from this site (https://apn.gishan.net/settings/1259_13_verizon_apn_settings_for_huawei_nexus_6p.php)...no luck
Using the same sim card (my personal one that previously worked in the 6P).....
The *#*#4636#*#* menu is showing Network Type: EvDo-rev.A on the 6P and LTE on Moto X
Speedtest on 6P shows - D:2.61 Mbps U: 1.13Mbps
Speed test on Moto x- D43.62Mbps U:20.37Mbps
Speed test on iPhone - D: 34.99 U:18.74
This tells me it's not a sim card issue but something changed on my 6P
Took it one step further, went all the way back to stock, wipe userdata, fastboot flashing lock. Reboot, still 3G.

I'm having the same problem with 6P on t-mobile since last week when I applied April update.
T-mobile say there are no issues with local cell towers, Google pointing finger at t-mobile
saying: " appears that the phone is receiving a signal that is switching the cellular data to Edge which is an older technology. It is possible that your device is receiving a signal from an older tower. Older towers do not work well with newer multi-band devices and this could be causing the issue".
I'm talking to t-mobile again to confirm they've not got any issues, but given the timing and given the fact that I see this on all the local towers I'm more suspicious about the phone/software, but we'll see.
I've tried factory reset, replacement sim reflashing a few different versions of stock rom.
I'm currently (slowly) working my through the logs in the bug report. It's slow going but interesting reading.
Do you remember what versions of the radio rom you've tried?

Dial *#*#4636#*#* and click the 3 dot menu on top right and choose band 6. Its possible that it got changed. Under preferred network type make sure its set to LTE/gsm/CDMA auto prl.

I have that network type selected. When i select a different band, should i expect something to happen? Do I need to restart?
Got a new sim card yesterday as well, no difference.
Looks like I may have fixed it!
Did not work:
-flashing images for MMB29P, MHC19I, MHC19Q, NPC91K (DP2 ANDROID N)
-New sim
-Messing with APNs, toggling airplane mode, selecting different bands in *#*#4636#*#* menu
I knew when I originally rec'd the phone, everything worked. So I figured, why not try the original original images?
Solution: Go back to stock! Flashed MDA89D and my LTE is back.
-As soon as it booted, I made test calls/texts. *#*#4636#*#* shows Network Type: LTE and Preferred Network Type: LTE/GSM/CDMA auto (PRL)
-APN page lists 6 APNs (it wasnt doing this when I only had 3G) and selected by default is VZWINTERNET
-Update to 6.0.1 immediately popped up as well. LTE still active after update! (This takes you to the December Security update. Then you go month-by-month to most recent)
My problem is obviously different as I'm on t-mobile but f.y.i.
I flashed October's image (MDB08K) which is an image that doesn't support the newer LTE bands (eg 12) and now I have LTE again.
Hi everyone !
Lately I went to a place were 3G/4G was not reachable and it is there that i noticed that my brand new Moto X play couldn't get any connection in 2G (GSM) mode even if the place was fully covered with 2G/EDGE (GSM)...
In 3G/4G there is no problem only on 2G (GSM).
I tried in the settings to put 2G (GSM) only and I can not get any signal even now that i'm back home ....
I tried a factory reset from the recovery it did not work :crying: Do you have an idea on how to solve that problem ?
I also tried to use the sim card with another phone in 2G (GSM) and there it works fine with maximal signal ....
Thanks ! :laugh:
Hallo,
I did a test and I got the same "problem".
Turned 4G into 3G...no problem.Still connected..
Turned 3G into 2G....no signal.
Turned 4G into 2G..no signal.
You can try to switch networktype in *#*#4636#*#*
No time for me now....I will try it later on the day.

I just tried it and turned the networktype to "GSM only" then i got no signal just like before. If i try to use another type like CDMA/GSM it connects to 3G and works but still the problem with the GSM/2G....
Hi guys. I'm not experiencing this problem on my XT1562. switching between bands is fine and working on my device. What kernels are you guys using?
I'm using the stock kernel, I just flashed the OTA (6.0.1) from the stock recovery
Same Problem, more information
For my Moto Play X I have a very similar problem:
4G works, but 3G and 2G do not. If I'm connected to a 4G network, I see that there is reception and can use all data transfer functions. But when I want to do a call, I get a timeout. When I'm in a place where there is no 4G network available, I see that I don't have signal - but the network is shown in the list of available networks for manual selection.
As I have a dual SIM variant (stock ROM, not a custom modification or "upgrade") my second SIM does work like a charm. I tried now and swapped the SIMs - and it seems that just the SIM1 slot is having those problems. The same SIM also works perfectly in the second SIM slot.
I also tries to reset just the network settings (an option provided by the stock ROM) but this didn't change anything.
Next step I'm currently working on is doing a factory reset - will take a while until backup and restore will enable me to see the real result. I'll keep you up to date....
UPDATE: factory reset didn't change anything - will send phone to repair now. :,-(
Facts:
- OnePlus 2 (European Edition, Germany)
- CM13 (13.0-20160721-NIGHTLY-oneplus2)
- Provider: Telekom (Congstar)
My OPT refused to switch to anything more then EDGE (2G) a few days ago. First I though the network was down but after a few days I checked with other phones and only mine wont switch to 3G or LTE.
When I tried to cheange the "prefered network" toggle, I switched it to 2G and now I can't switch it back to 3G or LTE. The options are still there but when I select them they instantly switch back to 2G. Even in the Advanced menu that you can enter by dialing *#*#4636#*#* I can't change it. The setting is fixed to "GSM only".
When I search for network I can only find 2G networks. In the Results are only Vodafone 2G and Congstar 2G which is my provider.
Does any one else have a similar problem and maybe a solution?
UPDATE:
I reflashed the stock image and everything worked there. Then reflashed cm13 and now I have the same error again. So it seems to be a software bug in cm13 not a hardware bug.
UPDATE 2:
I flashed the modem from stock again. Still not working. Than I disabled the modem from the service menu and enabled it again. Then it worked for a few days but then I was back to only 2G. Now the reflashing trick doesn't seem to work anymore.
I have no idea how to fix this does anyone have a clue? I can't be the only one with this problem.

You can't have 4g/lte active on both SIM cards, so solution is to put phone in flight mode, switch your primary SIM to 4g/lte which should put your secondary into 2g mode and then you're set.

What he said.
That's how I fixed it. Still wondering why this is possible with the stock firmware. At least I didn't notice the problem with stock.

because on stock it does this automatically. You can change the network type of the SIM on which data is enabled.
The other one wont even show you the option
