But the SIM card's that I try are from Portuguese carriers (Vodafone and TMN) but when I insert the Angola's SIM card the Phone ask's for a SIM lock network PIN.

Sim unlocking TMobile HTC One converted to google edition

I fully converted the TMobile HTC One to Google edition HTC One by changing the Model Id, CID and then flashed google edition firmware. This was a while ago and now I need to sim unlock the phone. I got the unlock code from TMobile but when i try to SIM unlock by inserting an ATT SIM it shows unsuccessful. Do I need to convert back to TMobile firmware in order to SIM unlock?
Anyone SIM unlocked a converted HTC One successfully?

You just need to flash any T-Mobile ROM and then do the sim unlock code .. After that is done you can go back and flash GE firmware.. All you need is the stock sense T-Mobile ROM then go back

[Q]Custom Rom on AT&T Desire 610 unlock SIM network?

Hi everyone. I'm new at this and was wondering if I install a custom Rom on AT&T HTC Desire 610 Go Phone, will I be able to use T-mobile instead of AT&T? Will it unlock or bypass the network so I don't need to get network unlock pin? I contacted AT&T customer service to unlock network pin but was told I need to activate service to get help with that. I really don't want to activate the phone only to get a network unlock code when I'll be using T-mobile after. If custom Rom won't do the trick is there a way to SIM-Unlock the phone or a tutorial? The Phone is brand new Bootloader unlocked with HTCDEV and rooted. Purchased at Target. Any help is appreciated. Thanks in advance to anyone with some insight on my dilemma
Nope. Requires supercid mode, which requires s-off, which we don't have yet. Only option is at&t. If you've got a friend with an at&t account in good standing, they might be able to do it for you.
