Hi, this is my first post.
Well, the problem I'm having is that I had been using my Htc slide with T-mobile and it worked just fine. Yesterday I unlocked it via IMEI to start using it with Claro -Puerto Rico-, so I switched to the Claro SIM card and it has no signal and it shows the (No Service) message, when the phone starts up it gets 2 white signal bars and quickly drops to no service, I checked the APN, the antenna, changing ROMs, set the band to GSM only, I've searched all over the net for solutions and nothing seems to work. :/ Then I switched back to the T-mobile SIM and I have no service either, so it seems as if unlocking it messed up the signal completely and it has rendered the phone useless.
Any ideas on what can be happening or how to solve this?
Thanks.

I believe it needs a hardware SIM unlock. This can only be done using a hardware device such as the XTC Clip, but I could be wrong. *shrug*

Hi Everyone.
Stock O2 ICS- rooted - bootloader unlocked
I've recently bought used HTC One V locked to O2. Problem is gsm service never worked for me.
WiFi, Bluetooth, GPS are fine but emergency call only.
I've tried different sim, 2 custom roms, hard reset and no lucky.
Under mobile network setting I cannot swap between WCDMA only - Auto - GSM only, it is sticked to WCDMA/GSM Auto only
When push *#*#4363#*#* Cannot change network mode too, WCDMA preferred fixed only, if going to radio band selection cannot choose any (Automatic, EURO Band etc) just got message "Set [automatic or any] Unsuccessful.
What is weird, When I turn mobile data on with correct APN for my provider (currently giffgaff) I have gprs running and can send and receive data, but with my other phones I had before my service has been alwaysfast as 3G and HSDPA, not "G" like now.
Please see below my screenshots, I've checked my mobile network with many apps and there is what I've found
Ok this may seem a very stupid question but it happened more than once. Are you using the little piece that covers the sim card? That has contacts in it, without it there is no signal

If you still have warranty, run a ruu so it goes back to stock, and take it to the HTC centre. If you are lucky they will recognize it as hardware problem and give you a new one. Remember to tell them it never worked, and if they ask about root or stuff, you don't know about it
No I don't have a warranty (it's second hand and a have no seller contact anymore), otherwise I would not asking here. Looking for somebody who solved this, if.
I've been using an S4 for about 2 weeks now, no problem. Last night I realized a text I sent never went through, and today my lock screen says "No Service" or "Searching" (despite the device showing full signal). I can't send/receive calls or texts, and I don't use a data connection. This SIM is also new (~2 weeks), and the device is neither rooted nor running a custom ROM. I've tried everything I could think of, like:
reboot
pull battery and SIM
confirmed APN settings on t-mobile site
tried alternate, non-"LTE" APN (epc tmobile com)
tried every network mode setting (GSM, GSM/WCDMA, etc.)
reset APN to default
turned on mobile data connection
manually scanned for networks (wouldn't connect to AT&T or T-mo)
select network automatically (wouldn't connect)
complete factory reset
I tried my SIM in another T-mo phone and it works; tried a different SIM in my S4 and it doesn't work. All other T-mo phones in my household are working fine. My S4 is definitely the problem here, but I don't see how the radio would just stop working after 2 weeks.
Has anyone else experienced/seen this? I never have, and it's driving me up a wall. I'm going to try my local T-mo store tomorrow, but I was hoping to fix it before then. Any help is greatly appreciated.
EDIT: I purchased the phone new on ebay. For a minute I thought the seller might have reported the phone stolen, but I checked the IMEI and it's clean.
Ive experience this but my service came back in about 25 minutes I did reset reboot battery pull sim pull it just came back on its own
Unrooted Samsung Galaxy S4 Up and Running
Rooted Mytouch 4G Slide retired
Rooted T-Mobile Sidekick Touch Obliterated
Rooted Mytouch 3G Slide Lost
Rooted T-Mobile G1 Dead
So I finally got to T-mobile today. Unfortunately, my hunch was right: the IMEI is blacklisted. Their in-house system must be more up to date than their web IMEI checker.
Time to solve this issue elsewhere.
hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.
Hi all, there is perhaps a response to this issue but my English is not very good since I'm Cuban, so sorry.
I have a GT-i9082L which sent me to Mexico and worked perfectly there, to get to Cuba no longer worked the mobile network, I thought that maybe should unlock it, bring it to a technician and he said that there was no problem to unlock it was the mobile.
I gave myself the task of making root and install your latest firmware for samsung perfect, but the phone still does not work just the mobile network, update the modem and still the same. I also installed other rom and nothing.
Without inserting any sim under 112 or 911 and pretends that this marking but no sound. if I insert a sim tells me that the network is not available.
I tried with other sim and does exactly the same.
No if glitch or software, does anyone h presented this problem?
Another curious fact is that even without wearing a sim gets in some places all signal lines.
appreciate any help.
thank you
I am in a fix here!!! Since long I have been facing this problem wherein, whenever I switch to 3G/4G mode, my phone looses network forever.. It seems to work perfectly fine in 2G mode.. I tried everything.. playing with radios, factory resetting and all the other help that I could get but in vain. I thought it is a hardware issue and since mine is an imported one, and I don't have warranty, I was avoiding to take it to a repair centre.. A week back, I went to Malaysia for a trip, and as I put a local SIM, my 3G starts working perfectly fine... I thought it could be a radio issue and as I came back to India, to my surprise my old local SIM was working fine in 3G mode yet again!!! I thought somehow my problem was sorted!!! It worked for 2 days and it is back to the old problem now.. no 3G whatsoever!!!! Please help me guys!!!
I was just browsing and I read an samsung user facing the same problem.. The carried switched his normal SIM to USIM.. and it started working.. could this be a valid issue?
try this.

If changing the settings in Phone Info did not help I have to agree that you need a different sim or different APN settings.
The same SIM works with the same APN in other phones... and even if it was an APN issue then the data would have been a problem.. But i don't even get network in 3G..
Sent from my HTC One_M8 using XDA Free mobile app
No help??

Post as much detail about your problem, if you want to get help.
What version M8?
Is it modded (custom ROM, root, s-off) or stock?
What region/carrier, and more importantly, what bands used for 3G and LTE?
What does it say for OS number in bootloader screen?
You've verified the SIM works for 3G and/or LTE on another device?

The SIM does work for 3G and LTE on other devices,
its modded with:

According to the following webpage, the 3G band used by Airtel is Tanzania is 2100 MHz (900 and 1800 listed are only for GSM/2G): http://www.worldtimezone.com/gsm.html
As this webpage also lists " 4G LTE TTCL" I will have to assume you got the info from the same or similar website. And that doesn't tell us what band your carrier uses for LTE/4G.
The 3G band 2100 MHz is supported by your current firmware. Make sure you have properly input the APN info for your carrier in the phone's settings.
LTE is trickier. Even with the proper band support and APN, you might not get LTE using an M8 version not intended for your region/carrier. But 3G should be possible.
I did but the 4G symbols is showed on the network bar once in a while. And it does not last long when it shows up!
For the TTCL sim card i can not access the network at all since it does not allow 2G services!
The same here. I face the problem yesterday =)) LTE icon show for the first time and then after a reboot, 3G and LTE signal gone forever =)) Now Edge only. Trying to fix it.
