losing signal

Hi.i got a touch cruise before 2 weeks and i face a serious problem.it loses signal from my provider all time and i must enter comm manager to enable and after disable airplane mode.sometimes it says that my sim is missing.anyone has an idea where the problem is?

I had this problem with my Orbit 1 and never did find a solution. Other SIM cards from other providers did not have the same problem. I also found that it was effected by other devices such as a transceiver that uses Tetra. I would love to know if there is a solution.

unfortunely everything i tried cannot solve the problem.i feel like i threw 800 usd into trash bin
its really a shame.i have nothing more to say

Hi again.I updated my radio rom to 1.58.25.14 but i still have the same problem.any ideas?
i still get the no service error and after sim is missing error

1 the sim is not compatible try getting a newer sim from the provider
2 the phone is defect

SIM Card Removed / Added - Restart Issue

Hello guys,
I've been having some issues with my Nexus 5 lately (about 2 weeks ago)... I've been getting the SIM Card Removed / Added error and completely kills my phone signal forcing me to restart the phone. This error happens over 40 times a day and from what I've been reading it's a software issue rather than a hardware problem. Has anyone found a fix for this problem?
Before I really did not care much about rebooting the phone and such, but lately it's forcing me to do it over 40 times a day and I barely get to do anything on it anymore. Any help is greatly appreciated.

had a user with a similar problem on Sprint. a new SIM fixed it.

I'm currently on T-Mobile and from what I read changing the SIM will not fix the problem.

From what you read? Did you at least try cleaning the SIM or try to change/swap it?

I have the same issue and tried everything . The sim works in others phones but not in the Huawei. And other Sims cards work on the huawei
Sent from my HUAWEI MT7-L09 using XDA Free mobile app

Has there been any luck? I am having the same issue however it worked the first time i put the sim in the phone but after that it no longer reads it and now every time i take it out there's multiple scratches on the sim card. I just bought it and was thinking about contacting Huawei about the warranty. Any thoughts?

You have probably managed somehow destroy the SIM card slot. I've noticed comparing to other phones that HAM7 SIM card slot is annoyingly tricky when putting your card in. It might have happened that the contacts have broken. I've read in some thread that there has been problems with it when putting card in. And no warranty applies here but it might depend on Huawei service.

I'm having the same problem with mine. I contacted Huawei and they actually answered me and said they were going to tell me where to send it in and that was the last I heard from them. Hell I'll pay to have it fixed just as long as it can be fixed.

Any luck? Was it the SIM card reader?
I think I have a similar problem, but I don't think I managed to damage the card reader.
Any help would be appreciated!

That problem is happening also with P8 Lite (phone from a friend of mine), SIM card is new, and no solution. Only reboot solves temporarily the problem

I am having a similar issue. I am overseas my phone is network unlocked. I brought a overseas SIM to get data. My phone does not recognise the new SIM. It still recognises the old SIM so I don't think there is a problem with the SIM reader. I have tried turning off and on and reboots etc. No luck. Really would like the data so that I can use google maps for navigating

No service and mobile network. Really no fix? :(

Hii... Have been searching forum but seems like no one has the answear
Galaxy s7 european version. Phone worked perfectly for 4 month and then suddenly I lost mobile network and service Tried hard reset, network setting reset ect. nothing helps Put simcard in different phone - everything is ok. I red that this problem most likely can t be fixed by software... Is that true? Can I try something else to fix this? Whats the cause?
Thanks for your time

I guess tomorrow I will return the device. Bought it from official carrier. Doubt it s blocked. Strange that no one has solution to this problem yet because there are quite a few similar posts online. :/

Hey there. I have the same issue with Vodafone Sim card AUSTRALIA. phone just stopped working all of a sudden. Why would they blacklist it? Other sim cards work on the phone.

have you been able to resolve your issue? what was the fix?

Has anyone got any solution of this? It's been quite a long with this issue, I've searched a lot of topics but no solution.

I have the same problem. Phone don't see simcard somehow. Flashed latest original firmware works for 1 min. Pull out trace with sim insert it again works for 2 min and stops working. When it works for small amount of time i think IMEI its not blocked and almost sure its software issue. Yesterday flashed different roms and CSC and modems no luck. SimCard changed for new one. Have someone some clue what to do ? I can provide logs if needed.
After instaling Samsung Phone Info app from market gsm wen't back online. Probably a coincident but when I go to Hardware screen ther was no modem model. I tap it few times. Close apk run it again modem went show itself after a while GSM signal is back.
After reboot no signal again. Then i make magic with phone info apk again and signal want back.
This apo make some sort of device discovery and reset modem device / driver or this is pure luck.

Weird network problem - signal drops

Hi everyone,
has any of you ever had network problems, as can be seen in the video?
For a few days now both network connections have been breaking down when I try to make a call. But that doesn't always happen. Sometimes I can make 10 calls in a row and everything is fine, and sometimes nothing works. It doesn't matter which SIM I use to make the call. The problem occurs with both cards. If that happens, then either directly when dialing a number, or immediately after hanging up.
I've never seen anything like this. And I wonder if it's the software, the SIM tray, one of the cards or the network operator itself.
Can anybody please help me? This is quite annoying.
PS: Sorry for the German settings. „Keine SIM-Karte“ = No SIM card // „Dienst nicht verfügbar“ = no service

Clear sim tool kit data
Network reset
Clear system cache
Make sure the access point names are correct

Thanks for the advice, but this didn't help.
I did these 4 steps, but the first time I tried to call, both connections dropped again. Can there be a hardware problem at all? Looks more like a software issue, doesn't it?

The sim card, the usual hardware suspect...
They can be damaged by ESD; handled like a stick of ram.
ESD may not manifest itself for weeks, months even years. Insults are cumulative.
It's not expensive but it is a pain, try to not damage it as it left the plant A-OK.
Just like ram sticks poor handling is the cause of almost all sim card failures.

So, am I getting you right? I just go to the store and have the SIM card replaced and everything should work again?
I've tried a few things now. If I set SIM 2 to GSM, everything is fine. The connection doesn't break. I believe it is the 3G connection. And that's why these crashes could occur when I make calls. SIM 2 doesn't support VoLTE, so it switches to 3G.
EDIT: I've tried different things now. I swapped SIM 1 and 2 back and forth. I also used my two SIM cards alternately with a third SIM card. The problem persists. Could a hard reset help or should I send the device for repairs straight away?

Same problem here. Setting sim 1 to GSM only, and sim2 to LTE fixed my problem for a while. This has something to do with dual sim handling.

This is soooo anoying. Have you had this problem for a long time or did it only come recently? Could this have something to do with a recent update?

I bought the phone a month ago, and while I was setting it up it received 5 updates including android 11. So I have no experience prior to Android 11.

Damn, same here.

Have you tried cleaning the sim cards with rubbing alcohol?
Then put them back without touching the metal contacts.

No, I don't see any point in doing that. I swapped the SIM cards and even tried other cards and the problem was still there. If something had to be cleaned, it would be the SIM tray. But as already written, there are no disconnections when a SIM is operated in 2G. I think that rather means that it is a software problem.

I have this same problem with phone dropping off the network. For me it started after the first Android 11 update. I have full signal levels at home but if I try to make a call signal level for both sim cards drops and I get a message that mobile network is not available. Doesn't happen always but pretty often.
I'm pretty sure it has something to do with how the phone handles dual-sim operations...

I am glad, I am not the only one, who is facing this problem. I already thought, I have to send my phone back. So, we have to wait for a fix.

Must be patient. There is also bluetooth problem(disconnecting from devices). It looks like they were too fast with android 11.

Since the last update(.159), i also have the drop out problem. Starting to feel sorry for buying it...

So, let's hope the new .222 update, which has just arrived, will fix this.
EDIT: no, it doesn't.

Yeah, I even had to restart after the update, in order for the second SIM to become active...
Edit - and the problem is even worse. Almost after every incoming call I lose signal to both sims...
Edit II - I wanted to try to switch sim 2 to gsm only network, and noticed that there's 5G available for it too, after the update. Before that there wasn't such an option....

Since I use the second SIM only for business calls, I have already set it to GSM only. Today I noticed that I still have outages. So apparently to force 2G is no longer of any use. :/
About 5G: It has been active on my device since I got it. Perhaps there was an update on this from your carrier.
