Hi,
I'm a quite newbie in the htc android tweaking world, so please be a bit understanding.
I know that there was a thread like this on this forum, but I couldn't find now. I'm sorry for that. If anyone can point me that thread, I will paste my post there, and ask for closing this one. I know that it is annoying when users create multiple threads with the same topic.
Well, I bought my phone on an auction as British T-mobile branded, but sim lock has been removed. I used it in Poland without problem, but when I got to Belgium I started to have major issues with Base network.
Since the phone had simlock removed not legal way, I S-offed with revolutionary (my HBOOT since then is in version 6.something - is this good or bad?), then rooted, finally debranded by installing original, signed Europe ROM, although I tried several roms before.
I used ClockworkMod as my recovery tool, but recently I read that it is deprecated, so I flashed it with 4ext recovery. I'm happier with the new tool.
Anyway, My problem is that before I could not use any simcard from BASE, the phone refused to connect saying that sim card refuses the connection.
It was with any andy version, so I actually applied the 1.47.401.4 update that everyone hates, and I didn't see any difference.
Then, very recently I found a post about a new radio version 20.48.300822U_3822.09.08.20_M. I applied it, and also copied the RIL files. It got better, I finally can connect. I had to drink for that Two months of fighting...
But every time the signal drops badly, the phone disconnects from the network and refuses to connect again saying that sim card doesn't allow connecting this network, and shows notification that BASE network is unavailable. Despite that, GPRS data connection is active, and I can connect to internet. Isn't that odd?
Then I need to reboot to 4EXT, and whipe Cache and Dalvik cache. It usually happens once per day - at my work, where I have quite network signal. Supprisingly after cache whiping, the phone can connect, and it seems that signal strength gets better...
I'm glad that after clearing the cache everything works, but I would be even more happy if I wouldn't have to do it... Does anyone know the problem? Has experienced something like this? Has a solution?
Should I use the new 2.3.5 based official rom? Can I transfer data somehow, so when I flash the phone, I still have the data that was there before flashing?
Hey, i'm on Mobile Vikings wich uses the BASE network but i never had anything like this before, could it be a kernel issue?

In short:
My phone was original British T-Mobile branded. I s-off my phone, rooted, changed roms but I still had no connectivity to Base in Belgium. I tried experimental roms, original roms, branded roms, radios... but nothing changed. After switching to original HTC European rom, applying 1.47.401.4 update and flashing the newest radio, I have connectivity, but still in bad signal range, my phone would disconnect from Base, and display me a message that the sim card doesn't allow connecting to this network. Then I need to boot to 4EXT, clear cache and dalvik cache, and after reboot everything works fine for a day or two...
Update:
Today clearing cache didn't work... After searching for network, I select BASE and I get a message saying that sim card refuses to connect to this network. Clearing cache, going to flight mode, just restarting the phone - nothing works... What else can I do?
There is one another thing I find weird - in mobile networks settings, every time I select network mode WCMDA or GSM, it always goes back to "WCMDA/GSM Auto" and I can't chage that.
Buy proximus or mobistar. I reccomend mobistar, best signal in BE

Yeah, but they have expensive internet. If I had just for calls, I would not buy belgian sim card at all, but use my polish number. Call prices are not that much different in roaming...
By the way, I switched to the new, 2.3.5 OTA update based rom by proxuser, but still no luck.
After many hours of stuggling, searching for answers - I found another thing that helps me: sim card needs to have a pin lock enabled. That's crazy, but works - When I loose my connectivity (described above), I reboot the phone, enter pin and everything works fine... sometimes I need to switch to a drifferent pin locked card first...
It would be better if I had not to do it everytime I loose range... So I see that sim settings are also somehow cached and switching to other sim card that has pin enabled cleans that cache. is there a way to clean that cache without having to switch sim cards?
Where can I find this cache? is it a file that could be deleted (or cleared)? formatting /cache partition, as well as clearing Dalvik cache didn't work, so I guess it is not there...
Because the procedure to renew the connection looks now like this:
1. turn off the phone
2. enter sim card that you know that will connect
2. boot into recovery, wipe cache and dalvik cache, reboot
3. provide pin and wait until it connects to a network
4. power off, switch card to the belgian one, power on
5. wait until it connects by it self. if it doesn't start from point 1...
it usually catches after 1 or second time...
agh, ity only worked for some time... now nothing works... I can not even connect to BASE using any other sim cards that are in roaming... I'm able to connect with other mobile phones, but not this... But it connects to Mobistar and Proximus without problems... I'm suspecting some kind of a defect that appears only with this network. But since I don't have warranty to that phone, I can't send it to the service...
I will try to return to stock rom again...
Now I'm using the phone with my Polish sim card in roaming, but actually I can't use internet then, and all I wanted it for was mobile networking... For a phone just for calling and sending messages any other phone that costs half of the price would be ok...
Hi guys,
I've tried searching but have not found the answer. I successfully rooted and loaded AOKP, as well as CM10 and one other ROM. On all of them, I can make calls and use wi-fi, but can't get mobile data. The signal bar shows "3G" and "H+" at times, but never turns blue when wi-fi is off. I've checked http://support.t-mobile.com/docs/DOC-1976 (t-mobile site) which includes instructions on APN settings for data and picture mail, but that didn't seem to solve the problem. I've also tried turning Airplane Mode on and off, and I've done a factory reset and cleared Dalvik cache for each ROM. The SIM card is about 4 years old, if that matters.
Thanks a lot for the help!
Sounds like the sim card my sim card is less than a year old and randomly my phone doesn't have network and a message comes up and says to clean my simcard because its dirty or corrupt. So I turn my phone off take out the sim wipe it on my pants lol and insert it back in and its fine after that. I would get a new sim and try it out or use a friends sim and see if it works correctly if not then it sounds like the sim port on the phone itself.

Hey there!
i had a dual sim android phone... china made. it runs android 2.2 froyo and it is super sluggish. but it is just enough for making calls, sms, app developing and also document writing.
just because i don't use a sim card for this phone in the past, i never knew this problem.
now, i use a sim card, at sim 1. it works well, the signal is strong, and the data connection is also great. The only problem is when i open up apps that eat up my ram, such as kingsoft office, or any games, it shows this at the notification bar.
"Sim 1 restricted access changed."
And immediately i lost my signal and also data connection. this sucks because my mum always says that the phone call never works. but after a few seconds or minutes, it is back again. and when i open up a new app or installing a new app, this happens again.
please help!
thanks.
Hi All.
I got the dual sim version last week & got myself a new nano sim card from Vodafone. Believe me, they're not easy to find in India.
So I put the sim in Slot 1 & waited for activation. But even after getting the activation message on my alternate number, the phone shows a "x" icon next to the signal meter.
I tinkered around with the network modes, basically trying the various combinations. Even played with the Network options in the Testing Mode. But still no luck. Finally, i switched the sim to Slot 2, and behold! I have reception!! Worked like a charm!
But then i find out Slot 2 doesn't support 3G/HSPDA. So i wanted to try and get Slot 1 to work again. Tinkered around again with the various modes, but to no avail.
The worst part is, now even Slot 2 has stopped working!!
I have no clue whats happening here. Is there a particular network setting that i'm missing, or am i dealing with a dodgy sim card??
Any help & inputs are appreciated.
Thanks

Got a replacement from HTC. Messed up "capture unit"
As of yesterday, my mobile data has stopped working. I can still make calls, and according to Net Analyzer the network type was LTE.
I flashed to 930U from 930VL a few weeks ago, but mobile data seemed to have been working fine in the interim. Any idea what could be causing this?
I do have mobile data on and did try toggling it, I have tried rebooting the phone, and I cannot edit my APN settings, but it's using "Tracfone - Verizon / VZWINTERNET".
Any ideas/similar problems/solutions are appreciated!
You haven't got anything like battery / network data saver turned on?
Changed anything in the developer settings?
Got another phone you can put the SIM in and make sure it's not a SIM issue?

Data saver is off, and I don't think I've changed anything in the developer settings.
I'll have to borrow someone's phone to check the SIM. What does it mean if it does or doesn't have mobile data in theirs?
If it works in theirs then you know it's probably your phone, if it doesn't work in theirs then you know your phone is probably okay (assuming their phone isn't carrier locked).
Surprising (& confusing) updates
Service in my area got a little loopy today during a large storm. We lost power, and so WiFi, at which point I looked at my phone and it had working 3G. Later, it showed LTE, but no mobile data. Then working 3G again, which I took a screenshot of. Since then I've had LTE & EVDO-A, both non-functional. What the heck is going on here?
Now back to working EVDO-A 3G, for some reason...

Edit: 3G is working reliably, and LTE is down.
