Phone shows no network with working sim card in it!!

ronnyzilker · Jun 1, 2013

So I have a Note 2 and a HTC one, for about three weeks I used my HTC one and then i switched back to my note 2. Yesterday I wanted to use my HTC one but every time I insert the sim card I get a no service message. what can I do to fix this?
I did not root the phone BTW.

Have you found a resolution? I just ran into the same problem.

Phone was working great, then one Sunday afternoon it just stopped getting a signal. It's not the SIM as it works fine in my old SGSII (had to make SIM adapter). I am rooted and unlocked and running non stock recovery but still on stock kernel/radio. Haven't contacted HTC yet for obvious reasons.

I've had this happen a lot with my phone on tmobile. I live in a concrete basement apartment where there's no reception and if the phone goes more than 15 hours without any signal I almost always(80%ish) have to call tmobile and have them deactivate/reactivate the sim from their end.

A fix you can try that they swear "usually works" is go to settings/mobile data/network operators/search automatically

If that doesn't work then try settings/mobile data/access point names/menu/reset to default

Apparently these settings can be reset pretty easily when the phone doesn't connect to a network for a bit, but all this might just be a tmobile thing

I have a bit different problem - I bought HTC One from T-mobile and unlocked it. I tooked it with me to Europe and device does work with american sim (ATT and TMO) but it wont recognize any of my national carriers. Insterting simcards(perfectly working) does not give me reception or anything. Sim cards are the same thing in EU and US I think - also those are GSM phones. I have friends having same problems with their S4 from AT&T in Europe. Does anybody know something to help make this device work?

OP - this happened to my Wife's phone for no apparent reason one day. I simply removed & reinserted the SIM and rebooted a couple of times, hasn't had a problem since.

I changed my SIM for a new one. Seems like a new SIM cards are a bit different from the old ones because after I did that I had no problems

Same problem here. I am on paranoid android though so maybe that has something to do with it. When I go into the settings to connect to the t mobile network, it says "your sim card is not authorized" or something like that. Maybe it's cuz I haven't paid my bill for 2 months? Lol but I don't think that's reason for them to block my sim :/

I had the same problem and I had to restart my phone sometimes several times a day, sometimes I had to remove the sim card enclosure and reinsert it in order for my phone to get a signal. So I contacted HTC and they told me that I probably had a defective sim card enclosure so they sent me a new one. After I installed the new sim card enclosure with the same sim card I had before the problem went away. I've been without any problems for the past four months or so since I got the replacement sim enclosure

type *#*#4636#*#* -> phone information -> make sure GSM/WCDMA/LTE Auto selected and Turn off radio

If you see turn on radio click that to turn on the radio. Is some cases the radio gets turned off and a reboot doesnt fix. This is the only way I know to recover it.

Make sure your Apn is set up correctly. If you go to settings>Mobile Data>APN you can see your apn and compare it to other tmoblie ones

Same issue with M9. Radio is off and pressing that button does nothing. Radio will not turn on. Any ideas?

Radio chip

I wonder if anyone can help please. My M7 can't connect to the network. The radio isn't turned off, I checked using the code given by Shane_pcs, so I know it is a hardware problem. I suspect the radio chip has worked loose somehow and isn't making contact like it should. Any tips on how to resolve this please? I have seen a tear down of the M7, but don't know if anyone on here has attempted to secure the radio chip before...not even sure what the chip itself looks like. Any ideas please? Thank you.
