Successfully unlocked O2 XDA II but can't make/receive calls

Hi,
I've tried both the 1.5 and 1.6 unlockers and both report success. I have fitted a Vodafone sim and both the sim and network are recognised.
However, if I try making a call the screen shows 'Dialing..' then goes straight to 'Call ended'. If I try phoning the Vodafone number then it is reported as unable to connect. I have tried both soft and hard reset.
The Vodafone sim is valid and works fine in another phone (I no longer have the original O2 sim , it was on a company contract that has been cancelled).
Do I need to set anything to use the Vodafone network or any ideas on gettting this running as a phone again?
Thanks.

Just noticed that under Phone Settings it says Phone Number: Not Available...?

Problems logging on to vodafone HSDPA

hi everyone..
can someone help?
i have a new sim card from a german provider (moobicent), who offer HSDPA flatrate using vodafone's network.
i insert the sim card in a normal nokia mobile phone, enter my PIN and the phone (as to be expected), logs into the vodafone network.
i insert the SIM into my HTC hermes (of course it's unlocked - it's also running the ROM TNT Pro 2), when i put in the PIN, the phone looks for network and after approx 300 seconds, i get the PIN screen again.
can anybody tell me why my Hermes won't logon to the network? (i have used all sorts of SIMS from various providers, never with any problems).
HELP!
thanks & regards.

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...

Issues with sim2 on s HTC one M8 dual sim

Hello
I hope this is the right place to ask and I feel at this point I have been searching Google dry over the past week.
I have a HTC one m8 with dual SIM, as I live in Sweden and work in Denmark, I have a Swedish tre.se in SIM1 and then a Danish 3.dk in SIM2
While I'm in Denmark, both SIM card works and connects to their network, but the second I enter Sweden, SIM2 won't find a connection.
I tried to switch the two cards, but then it's just the Swedish card in SIM2 that won't connect.
From what I have been able to Google , SIM2 should only be using 2g network, but this should be a problem for either of the subscriptions as far as I know.
Is there some special trick, setting or some I need to do to make it connect to 2g
It is original OS on it. I unfortunately can't root it, as my company mail will detect it and block my access. (Worx home by Citrix + touchdown)
What I have tested so far:
Factory reset of the phone.
New SIM card for both cards.
Activate and deactivate flight mode.
Deactivate and activate each SIM from the dual SIM manager.
Switch cards in slots (1->2 and 2->1).
Disable SIM1 ( SIM 2 still didn't connect)
I have also contacted each phone company, but they were to no use and just said it should work hehe
Any suggestions or ideas ? I'm open to all suggestions that doesn't involve getting another phone
Also this is not one of the cheap Chinese dual SIM versions.
Thanks

I may have managed to get a little closer to the cause.
It seems that SIM2 is actually only running over GSM / 2G for god knows what reason, and that is not supported by my phone company i Sweden, which is why it only works in Denmark.
I will try with another phone company called TDC and see if they have the same issues over there or else its bye bye useless dual sim

GSM service stopped working ('No service'), even though SIM loaded

Hey guys,
I've got a problem.
My s4 mini stopped loading cell signal from GSM network service. The SIM is loaded, as I can see it even in some programmes like Network Info. It even shows the name of the operator.
Even though the SIM card is loaded (it does NOT show "no sim card" error), I cannot get any service. Used 2 different network service providers, but still nothing. I changed GSM antenas and also SIM+SDcard slots on the motherboard, but still nothing.
What can the cause be, any idea?
Thanks.
