Your SIM card does not allow a connection to this network

Hello,
I bought a DHD online and when I put the SIM card the phone will not connect to the network.
The same SIM card in my other HTC's works without problems.
With other cards of the same network but the problem perch, but with cards from other networks the problem does not occur.
When I try to choose my network and the error that appears is "Your SIM card does not allow a connection to this network"
Please, anyone can help me?
I have seen this happen with stolen phones... Hope you purchased from reputed seller...

"No Signal" message - but phone detects SIM cards

Hi,
Please can someone help? I have an unlocked HTC 8S phone (purchased from eBay), but no matter which SIM I use I get a "No Signal" message on the phone.
The phone detects the SIM cards (I've tried Three, Sainsburys, and O2) and it downloads the connection/configuration data, but I get a "No Signal" message - so I can't make calls or send texts. I can go on the Internet though...
Is there a problem with SIM card slot? Maybe the aerial?
Thinking about it now, perhaps the phone was stolen and original owner has blocked it(?) Would the above issues be as a result of a blocked phone?
Thanks,
Paul

[Q] ee kestrel/huaweo g535 dual sim adapter not switching

brought a cheap adapter from ebay(copy of a magic sim i think) itworks on my very old eclair phone(even thought not suppose to) but when i insert it into my unlocked kestrel it defaults to sim 2 but doesnt install software to swtich it. if i take out sim 2, sim1 works fine so it isnt a connection issue.
tried a few multisim appsfrom playstore which dont work!
was wondering if emotion ui was stopping it installing as theres no app draw.
i have no idea how to switch to 007 mode either:s

SIM2 Not Working

Hi all,
Just got my Zenfone 2 yesterday and was super stoked, however the SIM2 component is not working. I have two SIM cards, one with Telus and one with Virgin Mobile. (Canadian carriers). No matter which order I put them in, the SIM2 card never works. The Zenfone 2 is able to identify the phone number associated with the SIM card in the SIM2 slot, but it is unable to actually make a network connection.
Anyone know how to get SIM2 working?
just update to the latest rom... I did and got my Sim1 working again!!

SIM2 is 2g only. So it needs to be Rogers (or network that uses Rogers) to work

Only SIM card slot 1 can access 3G/4G/LTE data. SIM card slot 2 can only be used for 2G service which include voice and basic text messaging (Not multimedia messaging services MMS or internet browsing). http://www.asus.com/us/Phones/ZenFone_2_ZE551ML/HelpDesk_knowledge/

I know this is an old thread but i was wondering if anyone has found a solution to this issue? I am having the same issue trying to get Sim2 to recognize a network. The number on the Sim card is recognized. I have tried switching the cards around and the result is always the same. Both providers that I am with are in Canada. One sim is with Bell and the second is with Virgin Mobile.
Are you saying you can't even make calls on sim2?

Network not working suddenly

Hi, I'm facing a serious problem with my Redmi Note 9 pro max. Suddenly the SIM cards are not detected (Both sims). Sometimes i get only 2g network in my 1st SIM. I have a Airtel sim on SIM 1 and JIO on SIM2. I tried using other sim cards as well but nothing seems to help. It just happened suddenly. The phone is brand new. I can't flash using flash tool because it needs sim card to send some info in developer options. I need help!
