3g Issue - UNUSUAL

Basically, my N1 when on stock worked perfectly with 3g, yes sometimes it was a bit patchy but it worked. I am using my old blackberry sim (UK), with the internet converted from bberry internet to normal.
Everything was going fine until I put my brother's orange sim in my phone (UK) [he also has a stock nexus, although at the time i was on 5.0.0.3 CM] to see if it was just his phone which had a 3g issue. I never managed to pick up 3g while his sim was in my phone, even though 2 blackberry bolds sitting next to it with orange sims in had perfect 3g.
ANYWAY THATS NOT THE ISSUE.
After replacing my sim in my phone, Ive never since had 3g, ever, even on routes I know the signal is immense.
What I want to know is 1) what would swapping sims have done to the phone, 2) what I can do to possibly reverse it so I can enjoy my 3g again

I haven't had this same problem but if I were you I would go to your carrier and get a replacement SIM card. The last time I had a weird issue like this I replaced my SIM and all of a sudden I got pure 3G signals everywhere where I hadn't before. If you get the new SIM and it still doesn't work, try wiping and install a completely different ROM (perferably stock) and see what happens.
Hope this helps!

But before I put my brothers sim in my phone, my sim worked perfectly fine, so I was thinking it was more likely to be phone than my sim?

Anyone have any ideas?

his sim seems to have disabled 3g somehow in your phone, though I've never heard me that before. have you gone into the info menu and seen if your 3g is still enabled? *#*#4636#*#* on your dialpad.

WHOOPs, yeah I had it off [while we were testing etc] and sort of forgot :/ Which setting is it meant to be on, GSM/CDMA auto?

you want it to be on WCDMA Preferred.

I've set it correctly now, and am getting 'H'. I didn't actually realise that it is a type of 3g network, however I am SURE It used to say '3g'. UK O2 if it makes a difference.

well H stands for HSDPA which is what some ROMs show. so have you flashed to a different custom ROM? either way you are getting correct high speed network, so no worries. my nexus only says 3G even when i'm on HSDPA.

How did you get the SIM unlocked in the first place?

This is probably because T-mob covers only particular places the frequencies this phone uses http://theunlockr.com/2013/07/05/htc-one-sprint-specs/ vs t-mob https://t-mobile.jive-mobile.com/#jive-document?content=/api/core/v2/documents/4988

Is there any solution for this problem ?
Is there anything I can do to fix this problem ? (different rom or radio...etc..) Or I have to give up the phone... Cause it is too much headache to "searching for network" all the time and miss all the call with no service on the phone without knowing..
Thanks

well, I am not an expert on the tmobiles network, but going by what lazybozz, said, I seem to remember tmobile using different bands than the other carriers, so what you may be experiencing, is the phone being in the vicinity of multiple towers, but not all of them are within the band that the phone supports. So its like the phone doesnt even see those towers. On a side note, this issue caused alot of chaos for those who unlocked iphones about 3 years ago, they could use EDGE on tmobiles network but not 3G, so i assume this is a similar situation. So long story short, yeah you probably cant fix the problem, unless you get a quad band phone. I could be wrong, but it does sound like a logical reason for the issue you are having.

as elvisypi said above, Its the freq that T-mobile operates on in that area. If your getting T-mobile at all in the states then you have already flashed a radio. However flashing any other radio is not going to give you the freq that tmobile uses, Its not a software limitation its a physical hardware limitation.

Thanks for your reply, do you know any app out there that monitor and alarm you when the network or signal is lost ? That works with 4.3 ?That way at least you know the phone is offline ... some of the apps I tried is anything at all ...
Thanks

Have you tried an app like tasker? Its essentially an automation app. It isnt jist for your use. Its for many different functions. Jist look on the app store for tasker. That might help

Lost LTE with *228

As crazy as it sounds, I was experimenting with roaming ability and did a *228 and #2 on my phone with Verizon. Since I did that LTE went away all I see now is 3G
Did not change the APN only have one and set on LTE for network....
Could I have messed up my PRL but I thought the PRL is now on the SIM?

whats a *228 and a #2???

*228 is NOT supposed to be used with a 4G SIM Card, you may have broke your SIM.

This hasn't worked on any lte device, why do people keep trying it? You need a new sim.

Sounds like my man is right has broken the sim even putting it in iPhone still comes up 3g when it did LTE was the same phone I used to get a nano sim. Off to Verizon see if I can get a new sim.

I knew this was a bonehead move thinking I could get volte work after updating radio. Cause not listening to my inner man!

Similar thing happened to me as well, after I updated to 5.1. Worked good for a day then all of a sudden I couldn't receive calls no more. I could make calls, text and use data. I called Verizon and they reset some things and the service completely went away, then we got disconnected. After calling back the rep said my sim got broken somehow and told me to go the Verizon store and get a new one. i think the first rep disabled something and couldnt get it back on.
New sim was activated in another phone then put into the Nexus 6 and all was good. Funny thing is I didn't do the *228 thing and my LTE was still showing when I stopped receiveing calls.

Can't make calls on VZW after switching back from Fi

I decided to give Project Fi a try after the word came down about Verizon raising the rates for unlimited data plans. Long story short, it's not for me. The coverage stinks in the areas I travel. Battery life took a big hit due to it having trouble finding and keeping a signal. I thought it would be better having looked at the TMo coverage maps. Anyway, that's a different topic.
I hadn't canceled my Verizon account so I put that SIM back in and it seems like I am connected to Verizon's network again. All the texts sent to that number came through once the phone was turned on with the VZW SIM back in. However, I can't make any calls. I get an operator error about being unable to complete the call. The Cellular Network Settings only has a roaming setting. Don't have the Enhanced VoLTE option and the other things I had prior to switching to Fi. Did the *#*#4636#*#* thing to try turning the radio off and on, turning on the VoLTE provisioning flag, rebooted, etc. No change in my ability to make calls. Anyone have any ideas what I need to do to get voice calls working again? If it matters, I am on 5.1.1 LMY48T.

The solution is to go into the calls section of the dialer and disable the call assistant settings.
https://www.reddit.com/r/ProjectFi/...ing_between_verizon_and_project_fi_sim_cards/

OK, so I can make calls again by changing the setting above. But I am without simultaneous voice and data. Still missing most settings under Cellular Network. Any ideas on how to get that back? Is there anything I need to toggle in the *#*#4636#*#* menu?

I'm having the same problem. But the issue is my phone is operating In Ireland, I've never lived in the u.s but I don't have call assistant in my dialer settings...I have data and texts and can receive calls but can't dial out, I obviously don't have access to projectfi here in Ireland and it is installed on my phone but its disabled and always has been, really strange I flashed the ROM for marshmallow automatically suggested by NRT for my device, but I'm wondering if the rom I flashed was u.s. specific even though it didn't suggest that in the rom I flashed...it has me absolutely baffled.

This came up alot when the N6 was first released last year. You will need to factory wipe the phone, and then you will have full access to the Verizon network. There is an issue with putting in a Verizon SIM after using another carrier's SIM.. Not sure but it might have affected Sprint also. The posts are out there on XDA about this, if you dont trust me. You can search and find them.

Sorry for the late reply. Life got in the way of me checking back on this thread sooner.
I believe you about the factory reset fixing it. Was just hoping there was an easier way so I don't have to setup my phone again. Perhaps the Marshmallow OTA will fix it but who knows when we'll get that. I'm tired of dealing with the signal issues I have as a result of switching back and forth so I'm going to do the reset. Just to confirm, this is the option under Settings > Backup & reset, right? Or is it something I need to boot into recovery to do?

Note 5 at&t emergency calls only issue.

Hello. About a 4 months ago i have bought from eBay a note 5 at&t version. I live in Greece and my network operator is WIND GR. The phone works fine but from time to time i get an emergency calls only message. And i can't get and do a phone call. If i restart the phone everything goes to normal. Sometimes it goes on and off by itself (the problem).
Have been anyone experiencing the same issue? If the phone is incompatible with my network operator should it not work at all?

Did you tried to change the sim card? Maybe issue is from sim or from sim slot

My sim is new. When i purchased the phone i have changed my old sim with a new sim 4g compatible.

It happened again. And i am missing calls like this. I will smash it with a hammer

Go to settings, backup and reset, then reset only network settings, see if any better signal

Done that right now. Tomorrow i will get a new sim card and i will post if anything gets better. Thanks for the help.

Update of the situation. I have changed sim card 2 times. It still happening. My phone runs at nougat now and the problem still appears as before at 5 and 6 Android version. I currently gonna change service provider that has better and stronger signal. From what i have discovered. When the phone looses signal due too poor service provider signal sometimes it can't register to network by itself. If i enable airplane mode and then turn it off it comes back. Any clue? If it's hardware issue what can i change?

Should i have at the mobile networks auto detect or manual and my carrier?
