Good day! I have a strange problem with my VZW M8. Signal was suddenly gone. I tried bunch of gsm local sim cards(Philippines) but I don't have network signals at all. Tried manual search and found the networks to register it but no avail. And I tried to RUU and Factory reset via stock recovery. The problem still exists. What should I do. Please help Thanks!

When I got my HTC Touch Cruise, I put in my Vodafone SIM card. It did not mention anything about 3G, and internet was slow as hell (GPRS)
After Opera got stuck, and I hard resetted the device, I found out the 3G network was connected. I was happy with 3G and HSDPA. Now my connection was of a real good use.
But, when I switched it into airplane mode today, and then out, it only found GPRS network. That's strange.
I thought it was a temporary problem which would go away with a reset. Not.
Maybe if I'd try Manual network selection... Also no solution.
Now I am fed up with this. I already called Vodafone, they tried their best but couldn't help me any further.
Does this mean I have to hard reset my device again to use the 3G connection again
I had the same problem, when i called my carrier, they didn't know anything about the Polaris (including that it even exists)... But, the Hard Reset fixed it, and has been working like a charm after that. At first i thought it was a registry edit caused the problem, but couldn't reproduce it.
I Got the same problem afte ruse the "plane configuration" but after a hard reset nothing happened...
any idea?
Hi RobbinM,
This could be a number of things relating to your device your SIM or our network. There are a few things you can try to rule out some of these first.
Try doing a full manual roam first by selecting another network on your phone and then choosing Vodafone UK to update. Then try to reconnect to 3G.
After that, try your SIM in another 3G device to see if you're able to connect with that. If you are then it's likely to be a phone problem. If it still doesn't find 3G then you could try another SIM in your phone for Vodafone and see if that connects to 3G, if it does then it is possibly a SIM problem.
The only way to rule out a network problem would be if you can connect to 3G on another phone with your SIM.
After trying this, if you're still unable to connect to 3G at all with your SIM or another phone and SIM, we'd need to take a look at your account and check for possible 3G faults in your area.
To get in touch you can contact us using our online contact us form here on the Vodafone.co.uk website here. In the body of your e-mail somewhere use the code FIT135, this will then route the e-mail to our queue here to work for you. Remember to put the info in the contact form relating to your Vodafone mobile number, we'll then be able to have a look for you and get back without having to ask you for more info first.
We'll look out for your e-mail. Good luck with the tests above. Perhaps include the results in your e-mail to help us diagnose the problem.

I also tried hard reset like 5 times, in different ways, with or without SIM installed when resetting.... Still no 3G.
I contacted vodafone here, they told me it was a problem in the phone itself. But I'm not sure since a hard reset didn't solve anything.
I recently swapped my i9000 for an i9023. I'm unable to connect to the network from my phone though! If I go into mobile network settings and scan for network operators, I can see my operator listed there. When I select it, I get an error stating 'Can't connect to the network, try later.' I've done the following things to troubleshoot this issue:
1. Verified that the IMEI wasn't lost. The IMEI shown in the phone status matches that printed under the battery.
2. Checked in *#*#4636#*#* that the network type is 'GSM only'.
3. Tried the latest update (JZO54K, Baseband I9023XXKI1).
4. Tried with different SIM cards from different operators. None of them seem to be able to register onto their respective networks.
I haven't tried switching radios as I'm not sure which radios can be tried safely on the i9023. Can I try any of the radios in this link? http://forum.xda-developers.com/showthread.php?t=1116884
Edit: Tried with all the radios and three different operators. No joy
By the way, I'm in Bangalore, India and my operator is Idea. Uses GSM 900.
TIA!

Read my thread.. http://forum.xda-developers.com/showthread.php?p=31511891#post31511891
During my research I find out that is a phone "problem", that is incompatible with some SIM types (but the warranty won't help because the Sim module has no issues). If it's your case, there's nothing to do but sell the phone.
Thanks for the reply MicheleM42. From the looks of it, I think it might be a hardware issue in my case. I will be taking it over to Samsung tomorrow to have it checked. Sigh! Will need to reset it to the factory image now...
I posted this in the "any question" thread, I hope it's okay for me to post it here as a new topic too --
S6 920F 32GB, stock, not rooted.
I have an issue with connecting to mobile networks --
The handset is network unlocked, but with a sim from my preferred network inserted, the only way I can get it to register on a network is to put the phone in 2G ONLY mode.
If LTE or 3G are on, it won't manually or automatically register on any network. I've taken it to a phone shop and with a different SIM on the same network, the same issue is apparent.
SIMs from two other networks allow the handset to register on LTE/3G without any problems.
The network's customer care team were unable to help, I've reset it, I OTA updated to Marshmallow, no change.
Do I need to reflash modem firmware or something? This is driving me nuts.
Thanks.
hello,
I am from India and using Vodafone network. I am facing a very weird problem with my OPO. I am able to receive and use LTE ie I can use internet and send and receive messages.
But the problem starts when I try to make a call. As i dial a no. the phone switches to 3g and I receive a error saying NO NETWORK CONNECTION in about 5-7 seconds. To confirm this problem, I tried to switch to 3g only and 2g only in the network settings. Whenever I select 2g or 3g, my connection is lost and I cant even register to a network
I have tried many other sims including reliance, idea and another vodafone sim with the same result. I have flashed the stock COS file using fastboot to make my phone completely stock including clearing data, internal storage and system. I have tried a lot of roms which never used to give me such a error but the problem persists in all the roms
Please guys help me out
Thank you in advance

I managed to solve the same problem not a long time ago. At the end of this post there are several values you can write in nvram. Try experimenting with the ones.
If it did the trick just don't forget to make a backup of EFS partition
same problem, let me know if you resolve
I think you might need to unlock all bands. Check this out: http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031
Notes:*Those modifications need to be redone after radio*flashes.*
I will certainly try that..
But is it possible that the bands I need were unlocked earlier and now they are not, beacause 10 days earlier my 2g and 3g networking on this phone were working perfectly...
On that day I messed up a lot of settings in *#*#4646*#*# menu, could this be the possible reason that some of the bands are now locked???And I also want to tell you that all the options like WCDMA only GSM only etc which were earlier available in the menu are still available
Thanks your replies
Hey guys,
I have new Google Pixel 7 Pro, I'm living in Montenegro my Gsm Company is One Plus.

But phone can't connect to internet from sim card.
This is so bull****
What's the problem exactly?
I tried this solutions.
Rooted and I installed Network Signal Guru (I changed some band and other settings) but no luck
I installed VotLE patches
Tried factory reset
Tried wifi and network reset
Tried different sim cards

Update: I talked my GSM right now. I created new internet profile for connection on settings now working.. Omg it can't connect automatically.. You need set profile settings..
This questing should be closed. Thanks.
