Keep getting the message Sim 2 Not Allowed. It comes and goes, and eventually it reconnects either by restarting the phone or all on its own after anywhere from 30 seconds to a couple of minutes. I have a U.S. sim and U.K. sim.
I've reset the APN, Called EE to make sure the IMEI number isn't blocked, it isn't and they see no problems on their end. I've switched the cards around, it's fine for days. I've taken the cards out, then back it stops for a bit then restarts. I can go a few days no message then receive the message several times a day.
Anyone have any ideas? Is it just Samsung borking the network coding again? Hardware failure? I'm just at a loss.

Money is tight, phone broke, bought a T-Mobile Dash off Craig's list. I am a T-Mobile Customer. Tried my sim card in it before I bought it - made a call - no problem. Got home (8 miles away) and it couldn't stay connected. Searching, searching, searching. Tried husband's sim card - same thing. D/led manual to be sure sim card was properly seated. It was. Called, texted, emailed seller. No reply. Reset phone. Same issue. Switched Sim cards back and forth, back and forth. Was able to make one call for 10 seconds and then call dropped - no service. Now I'm out my money and still have no phone. Is there anyone out there with any ideas?
Update: opened case, wiggled battery, wiggled sim card, finally got some bars. Made a call successfully. Second call - call dropped as soon as connected. Third call - Call dropped before connected. Now it still shows bars but will not make call or send text. Please Please help. Somebody, Anybody??
You might want to perform a hard reset. See the sticky at the top of the page.

What rom r u using? Have you called T - mobile and see if they had any signal reception problems in your area?, cause it can be a dead spot reception area.
Have you tried manually searching for other networks. Where I live, you can occasionally see TMo towers, but I do better to connect to a non TMo tower and be set on manual search.

Same here
I had the same problem with my Dash, and I gave up on it a year ago.
Symptoms:
Phone randomly loses signal every few minutes, gets it back a few minutes later.
Sometimes when it loses signal, it shows a SIM error or no SIM installed icon.
Battery meter varies wildly.
Actions taken:
Purchased new battery.
Tried another known good SIM (my wife's SIM - worked great in her phone).
Flashed WM 6.0 and 6.1
Result: Look at my sig
Anyone else experience this or have any ideas on how to fix? I don't even need the phone anymore, but it still stumps me and annoys me that such an expensive phone (it was expensive when I bought it 2.5 years ago) would suddenly quit working.
Thanks for the reply - at least I'm not the only one. Not that it helps, but .... did your Dash ever work when you first bought it?
Worked wonderfully for a year. I loved it. It started my addiction to smartphones and constant connectivity.
Not sure if anyone else has had this problem but i randomly get mobile network drops once or twice a week. The phone works perfectly well but the mobile network just drops, you cannot scan for network at all. The only way i have found around it is to enable plane mode to drop all connections and then turn plane mode back off so the network starts up. This often takes between 5 - 10 mins for it to kick in.
Tried two roms but now back to stock but still happening.
Have you tried flashing the latest radio? They are listed in the dev section.
The recent OTA 1.21.405.2 update included a new radio I think. Did you put this on too?
Since then, I have also been having the network drop out. I am missing a lot of calls as a result. Prior to this update I had two months of problem-free operation on my stock 2.1 ROM.
From reading the google forums, this is a wide-spread issue. The light at the end of the tunnel seems to be that people updating to 2.2 froyo seem to see the problem stop. Two weeks to wait for us stock ROM boys according to the rumours then! Fingers crossed.
It's a bit embarrassing having this flashy toy when it struggles to be a phone at random intervals. At the weekend one of my less techy friends was waving his Nokia 6210i in my face saying, "At least I can make and recieve calls!". So I changed the language on his phone to Turkish when he left it lying about. The old ones are the best.
I am going to test the 1.21.405.2 theory by doing a factory reset later this week when I have time. Problem should persist if it is the new radio. Will post back with the results.
OK did a factory reset this morning. I left all my apps off, and did not set back up any google account business. I basically left it as a standard mobile phone.
Within 7 hours, guess what....yes it's lost the connection again. Strongly believe this is a radio problem. I'm too noob to know if I can flash the radio without rooting. Anyone?
I have since submitted my complaint with HTC CS. Will await their response, and post it here.
In the interim, turning airplane mode off and on again does regain the connection, and I have installed an app from the market place called "No Coverage Alert". It will now beep and buzz if I loose the connection so at least I will be aware every time it bombs out. Far from ideal but should do for now.
Watch this space.
Yes i have tried the two radios posted but i havent tried any international ones such as europe or asia. I still randomly get network drop and i need to turn radio off and back on again for it to pick up.
Maybe i should ask a chef if these drops are logged anywhere on the device so i can root in and look at the logs myself and diagnose what the network drop is on my phone.
Just to confirm, tried multiple radios and roms, i know exactly what i am doing all i would like is explaination of why it happens. It is not user error as i have tried with stock rom, no fancy apps etc to stop it from working or changing config.
its got something to do with the network radio libs that need a service restart. i am 100% sure if i rooted in and knew which service to restart it would work also
Erm.... this is a little embarrassing but I feel I need to own up to prevent misleading anyone. I have arranged with HTC customer support to send my Desire back for repair. They pick it up Monday.
I bought a cheap £10 phone to keep me going. It arrived this morning. After I had finished laughing at it, I put the SIM card in and powered up the phone.
"No SIM card instered" was the message it greeted me with. After numerous power-up and power downs, and some SIM card hoakee-coakee, it finally recognised the SIM card......then dropped the signal to Orange. EXACTLY what my HTC Desire did.
Doh.
I had tried the SIM card in another phone (my girlfriends Blackberry) when the problems first started and it had worked straight away. But the SIM card seems to be random in it's failures. Should have tested more rigorously.
Sorry guys but in my instance it seems I have simply a faulty SIM card. The first one I have ever had go wrong in 12 years, but there you go. I was too fast to blame Android/HTC.
A|ex, please try your SIM card in another handset. Do several power-ups to see if it goes wrong. Would explain why trying numerous radios/ROMs has not helped you.
Let me know?
I had the same issue. Talked all day and evening, then toyed around with the phone a little, flashed a new ROM, no connection. oO okay, that's weird. Tried 3 different ROMs, reset to factory settings. Went to Orange, the SIM was borked. Thankfully, getting a new one took all of 5 minutes and didn't cost me a dime.
Yep. Was the SIM card. The new one arrived from Orange this morning. Popped it in and it's working straight away. My 3G has even improved slightly I reckon.
Six hours of use and not one drop yet.
Thank god for that.
I was having issues in the last few weeks with having a data connection, after some hours/day suddenly my data connection wouldn't want to connect anymore because "the service is unavailable", every time i had to pull out the sim and put it back in and it would reconnect the data connection..
Except this time when i did it, it suddenly doesn't even want to connect to the normal network..
Looking at me sim, it seems kinda damaged already by 3 stripes that are carved into the sim.. (see attachment)
It might be that those pins that are connecting to the sim inside are too close on the sim tray?
Could this be indeed the issue that was causing my data to not connect too? Unfortunately i cannot test it with another sim, nobody near me uses a nano sim..
I can't imagine those lines would cause any damage to the contacts, it looks completely normal to me. It's just what happens when it's inserted and re-inserted numerous times.
I'm sure your carrier would give you a free replacement SIM, and it would be even easier if you have one of their stores nearby, where they can just give you another SIM card there and then.

Yeah i just ordered 2 free sims from 2 different providers, see if i have the same "Disconnected because service is unavailable" with my data connection...
It's really odd that it works for a few hours/days before it stops working each time.. except now.. still can't get any data connection, signal started working again after re-inserting the sim couple more times...
Now suddenly it's working again.. but for how long..
Could logcat detect the problem here if i keep it running?
Hello, I have the regular 7t model 128GB HD1905 and randomly, my phone will drop all connections. This is the 2nd occurrence of this issue, and I managed to grab a screen cap of it.
I don't know what causes it, as it happens randomly. 1st time I was on break at work, 2nd time I was visiting family for the holidays.
As you can see from the video, the SIM card is acting like it randomly disconnects/reconnects rapidly. Throwing it in and out of Airplane mode doesn't help, rebooting doesn't help; the only solution was taking out the SIM card, blowing inside the tray, and reinserting it.
The 2nd time it happened, I didn't have a SIM card ejector tool, but it seemed like it randomly went away.
I've had this unit replaced last week as it had a green tint defect, but my previous unit experienced this bug also.
I don't think it's an issue with the SIM card, as my OnePlus 6 reads my SIM card just fine for the previous year that I've used it.
Video of what happens: https://youtu.be/a1j-6o5ChLM
So I have a HD1925 otherwise known as the 5G McLaren. I had connectivity issues immediately with my first phone and I found that my mms wouldn't work, neither would voice calls if my carrier signal dropped at my house and I was connected to my wifi. So my new phone arrived, and voice calls will work on this phone but still no mms unless I'm connected to a carrier while on wifi. Don't have this issue work my regular 7pro. Neither does the rest of my family with iPhones. Haven't figured out yet what is wrong. Will update I've I find an answer.
I had to return the 6T because my LTE would disconnect/reconnect all day long. Now I have a 7T 1905 and had my first occurrence of this today in about 10 days. I'm REALLY hoping it was just a 1 time thing, or at least a very occasional thing. I'm on T-Mobile in the USA.
Hello,
Maybe you guys can help me out before I throw this phone in the dumpster.
So my phone started to overheat for no apparent reason and would shut off completely and I took it to the shop to repair,apparently the charging port was the issue, they fixed it for a reasonable price and it was all good.
Day went by with no problems and now today I cant make calls, text or use mobile data. The signal keeps going from 4 bars to 3 to 1 to the no entry sign for both sims.
I've tried swapping the sims, putting just 1 sim in i even factory reset the phone but still nothing, im not sure what else to do here. maybe my sim cards are interfering with each other or theres some obvious issue im missing?
I've tried both sim cards with another phone and both work fine, i instantly receive the configuration message from my phone provider as soon as i boot up the other phone with the sim in it but with the a50 im getting nothing.
No 4g no messages no calls nothing. Any help would be greatly appreciated. The phone is in near perfect condition bought it about 6 months ago and I dont really want to spend any more money taking it to the repair shops and i'll end up just buying another phone.
Thanks.
