restart after loss in service?

I just took a trip for the weekend and much of the area i travelled thru didnt have cell service. However I found that when my phone was in a cell service area it wasnt making calls. here is the scenario...
driving down the highway, my cell isnt finding a signal, it sets itself to the airplane setting & thus calls cant be made, my wife's curve has a signal & she's on the phone, so i turn the phone back on & try to make a call...it ends my calls before it rings. i try to wait to see if its a timing issue, 10 minutes lapses, wife still on phone, i try to make a call, no go.
i had to cut my phone off & cut it back on to get the phone to work?? it recognized a signal as i had 1 bar of signal reception on the tilt and my wife's curve had 2 bars. but it'd never start a call. i'd see that it said calling, 3-5 secs later it said call ended...
anyone have any idea as to why this would happen or why i'd be required to restart everytime i leave a cell service area & reenter one? any fixes? i searched for my title & found no results...

Are you on 3G or GSM when it fails? If it's on 3G, you could have that problem, try to switch to GSM only and see if it's better.

well as far as i know we're not getting 3g until may...but i do drive towards a 3g network, so it may have been switching over to 3g prior to driving into the back country?

i checked & the phone is actually set to gsm only already...so this cant be the issue. any other thoughts?

Wish I had an answer, but my phone does the same thing. I must reset the phone to get a signal

what rom are you on? the 162 htc/att rom? bcuz i know now i am having a problem i wasnt before. because there is a building downtown that doesnt get cell service in it, and i frequent that building. i never had the issue on my original tilt on the 158 (i believe) rom, but this rma came w/ 162 rom & now im having the issue in that bldg too. which goes to further prove its not the 3g network theory. its just a matter of losing signal & then getting signal back where i am experiencing the issue.
thanks for any help.

Today was day one with the new tilt and it didn't have the problem. However, my old one wasn't consistent one way or the other, either, so I'll have to give the new one some time.

(work for at&t) New phone will not fix this problem, nothin wrong w/ phone. U need to go to a local corp store and change the SIM and get someone who knows what they r doing so they put all of the SIM updates while plugged into the comp. OTA updates will never work w/o these initial updates.

I have an issue where i'm connected to the net (GPRS/hdspa) and occasionally i will lose the connection whislt the connection is still active..
No internet functions will work even when i reconnect
I have to then restart the phone to be able to use the internet again
Not the same issue but something similar

Same problem here. It is not possible to establish a 3G connection. If I set the BAND in the telephone Settings to GSM the connection is stable. If try to establish a 3g connection all further connection trys will fail.
I already changed my Kaiser, it did not help.
Update:
T-mobile will sent me a new sim card. Hope this will help...

[Q] no 4g or lte on stock or custom rom

So I've had this phone for almost a week now and I used to he able to get 4g LTE. But ever since I rooted it, I no longer get more than 3g. I now have bananacakes Holiraider 1.6 but I still don't get any higher than 3g. So my question is how do I get 4g and 4g lte. Oh and if anyone is using that custom Rom, is it possible to get faster than 1512? In his thread it shows you can clock it to 1566. Thanks a bunch I'm kinda new to this!

try dialing *#*#4636#*#* and see what your modem is set to, it should be GSM/WCDMA/LTE auto
you also may have an APN issue, verifiy that your APN is correct, perhaps contact your carrier for the correct APN settings for you phone and plan.

Well I'm now running a custom ROM. The apn is the same as other users and it does say the above. And yes I am in a 4G LTE area

Try doing the above and change to LTE only.
Then once you have 4G change it back. It should stay on 4G. I had to do this to get 4G on official rom.

Ok I just tried that but it wouldn't let me to switch it to LTE only. When I did, it switched it back to GSM/WCDMA/LTE auto. I'm just gonna relock my phone and set it back to the original stock rom and format my phone (yes I have the apps and stuff backed up). Because my actual mobile connection fluctuates on and off as well

the phone should be locked into the GSM/WCDMA/LTE setting. If you try to change it from that setting it just returns back. The phone will get instructions from the carrier's base station to tell it whether to be on LTE or just 4G/3G. Using *#*#4636#*#* under phone information, what is listed as the Network type?

It is locked in GSM/WCDM/LTE auto.

above that option it should tell you the network type. it is about half way between the "run ping test" button and the "Set Preferred Network type" option. Need to know what it says there.

Oh ok I see what you mean, it says HSDPA

make sure that you are in a active LTE area. toggle the radio off and on. the network type should change to LTE if it is available. remember that if you make a phone call your phone will drop back to just 4g/3g and it might take a second for it to switch back to LTE.

I live in Los Angeles so I'm like in the center of the LTE center in Southern California. But for some reason my phone won't get anything higher than 3G, and my actual cellphone reception toggles on and off randomly too.

It worked before. For the first 3 days atleast. And now all of the sudden it wouldn't work, so I rooted it and installed a custom ROM

Try one of WildChilds custom ROMS. LTE works on both and they're tailored to US users.

if the problem arised before you rooted and rom'd the phone I doubt the rom is the problem. there is always the chance that you have a bad radio.

That's what I'm thinking... What would I do about this?

i would verify your sim with another 4gLTE phone and vice versa.

Hrm... So it could be a Sim card problem eh? Unfortunately there are no other LTE devices for me to get a hold of... Would this be the only way?

it could be. i hope you have pulled battery/sim and then rebooted already. you can verify your phone with a known good sim and verify your sim with a known good phone. I would try your local at&t store. they might be able to help.

I have done it many times . Yeah I'm actually going to head over to the at&t store in a few minutes, I'll keep you posted. Thank you so much for your help! rft3ch!

I will be replacing my phone. I replaced the sim card and that wasn't the problem . The rep said that someone else came in with the same problem as well.

VZW Moto X not going on 4G

so i came from my GNEX and needed to cut the SIM from micro to nano. came out damn near perfect. put the cut SIm in my moto x and it worked. 4G comes on and all is well for about a minute or i use my data in anyways. it will instantly drop down to 3G. Verizon did the whole "Restart and factory reset" BS and nothing helped. they tried a new sim and it wouldnt accept it.... what do i do

so now that you have a new SIM card. the phone wont read it at all so you have no data what so ever?

I don't know much to help, but I noticed on my new Vzw Moto X that right after activation, my 4G light was on. I continued the setup and 4G turned off almost immediately. That was odd, but I was activating at home. I need to port in a number and visit a store, so I thought I would ask at that point. I was at home with WiFi. Anyway - I noticed that when WiFi is off, 4G is on. As soon as I turn on WiFi or connect to a WiFi access point, that 4G turns off. Could this be it?

i have data and everything is working fine, but its only 3g. ive tried a new sim, hard reset, changing my data from global to 3g/4g adn all i can get its 3g.... i mean it works but jsut annoying

have you done any major changes to the phone recently?
if you haven't done any changes then sounds like there end not yours. only thing left you could try would be to use one of the restore to stock zips and try flashing it and see if that fixes it.that file contains all the modem's and so forth.
also like the other guy said are you connected to wifi and are you even sure you get 4G at your current location. i would restore my device to stock with the correct zip and see if that fixes it.

Wrong post

I'm going to just try Verizon again and if they can't fix it demand a replacement... Why have a 4g phone when it's not using It

so after 2 new SIMS and 4 factory restarts, the VZW rep fixed what was wrong. now, time to see how long my battery life is with 4G on!

I have noted the same thing, and was curious.
Per VZW customer support today, that is normal operation.
The reasoning is as I expected:
Once you have a wifi connection (not just the wifi radio turned on), that connection will be responsible for data communications. The data capability of 4G is redundant, and the phone drops back to 3G operation to support phone only operations (voice, sms, e911, etc).
As I understand it, this should reduce both your battery usage, and of course VZW's tower's data load.

3g not working if radios set to 3g only?

I noticed if I go to the mobile networking settings and have it it on lte/3g if I leave a 4g area, 3g works ok. If I put the toggle specifically on 3g it shows I have 3g, but anytime I tried to search google or access a data connection the signal goes away and gives me the signal with an exclamation point. I tried finding info on this, but didn't see anything when I searched. Anyone else have this issue? I am on Sprint with the 64gb white device. Thanks

I leave mine on 3g due to the lame multiple text issue. It has no problem staying on 3g. Perhaps try updating your PRL/profile and see if that helps.

I don't have 3g either if I set it to 3g only. I don't leave lte service too often to test whether 3g works when it switches on its own. I may have to make a trip to the mountains to test it. I do know that my old Note 2 would loose lte after flashing tons over and over and I would have to flash back to 100% stock the factory reset from the settings app to fix it. I may try this with my Nexus, about time for a wipe anyway.

Factory reset does not fix it. Just noticed that I don't even get 3g when it is set on LTE. I'm gonna go talk to my cellular provider about it.

I don't know why it wouldn't work. You did update profile and PRL also right? Here's some shots of mine and it's working fine.

I have a bad Sim.....I also don't have a phone number as well..... I swiped with an old card I had and my number appeared, I guess I'll be visiting the store tomorrow to get a new one. Maybe it'll fix my 3g. Its also not wanting to let me pick 3g as an option now, just stays on LTE.

KB112 - Are you on sprint also? I updated prl/profile and no luck still. 3g still works if I am on lte and go into a 3g zone, but if I toggle it to 3g only I get no data. Wondering if its a sprint thing or a lollipop bug on Sprint, or a bad sim, missing feature activation.
Bluemgt06 - did a new sim fix it for you?

Sorry, didn't see this earlier. But yes, I am on Sprint. My 3G would work fine if I set to 3G only. Not sure why yours has issues with this?

Oddly I tried it today and it started working. I think it could have been some kind of issue with the tower/upgrades or a bug that a reset may fix on occasion perhaps.

Cash for Note 5 help!

I'll keep it short. I have rooted Sprint Note 5. Currently with TWRP recovery and MOAR rom. I called Sprint to "Unlock" the phone for me (wasn't financed, I purchased it outright on Swappa...previous owner apparently used it on Ting) and the unlock went through. Now, I'm not sure whether the unlock I did was a domestic unlock or just an unlock to use the phone overseas. My fault for not finding out.
Fast forward. I went over to MetroPCS yesterday with my Sprint Note 5. The sim card was accepted and I called MetroPCS so that they can register the IMEI of the phone in their database. I quickly tested data and sent a text but didn't bother making a phone call. Long story short for the life of me I cannot get a phone call to go through.
I've tried two different MetroPCS APN settings and messed with Network settings (LTE/CDMA and Automatic) The best I can do is get data working and text messaging but not phone calls. I went into MetroPCS today to see if one of the morons could see if they could do something with it. The guy went into Network Mode and changed it to the GSM/whatever option (don't have the phone in front of me ATM) and sure enough the phone was able to make a phone call and the data worked!
However, around 30 minutes later I try to use data to update an app in the PlayStore and I'm notified that I have no connection. I go back and forth between Network settings and I'm back to square one where I can only get data and messaging. The GSM Network Mode no longer shows a signal.
Soooooooo, if anyone can get me through this mess I will give $20 for your time and energy! I'm about to just flash stock Sprint firmware and sell this piece of crap on Ebay and get different phone for MetroPCS. This thread is my last attempt at finding a resolution!

@SantinoInc, have you checked with Sprint if they have locked the device?
What bands does Metro use for 4G/LTE and is it compatible with a Sprint-based device?
Try using 2G/3G mode instead of the 4G/LTE mode.

What rom are you using?
