Unlocking the HTC S620

I have a HTC S620 that is locked to T-mobile network.
I've purchased the unlock code from T-mobile and I want to unlock my device. But I have 3rd party security software on the phone so when I insert my Vodafone SIM an switch it on the screens flicks between the security software and the unlock code text box.
Is there any way to unlock the device with the T-mobile SIM still in the phone?
I have recently unlocked a Nokia device by inputting the +pw etc and the unlock code.
Is there a sequence I can follow like this for my S620?
Thank you

What to do with a sim unlock code?

Im about to call metro pcs for a sim unlock code so that I can use a t-mobile sim on the phone (it's the old type metro phone) and I'm wondering where would even put this code?
Call the customer support team and discuss this with them. They will help you with good suggestion.
Change The Sim Card Or put a Different Sim Card and Punch the code if the Device Ask you

Sim unlock so phone can be used on other networks

Is it possible to unlock the z3 xperia so that it can be used in other countries/mobile service providers ?
I have found sites online that offer a unlock code that you need to buy. just seeing if it's possible to do myself.
In theory Yes you can do it. It requires a tweak to remove the sim restriction so you can use other but you may be affected by LTE connectivity. Check the Z3V form to see

Is is possible to carrier unlock this phone

I am getting a xperia xa for my daughter but it is on the wrong carrier (2degrees NZ). Is there any free way to carrier unlock it?
The only free way to SIM unlock your Sony is by contacting your carrier and asking them to remove the network unlock enforced on your phone.
If they do not agree and they don't unlock your phone, you will have to pay for one type of service or another to unlock your phone, either a local phone repair shop or online unlock code provider.

Network unlock by flashing?

Hi,
I have a Sony XA 73111 which is an ex-business phone and therefor EE wont unlock it unless the original account holder requests it. As i'm not in contact with the original account holder my only option is to buy a direct unlock which is about £25 - Would like to avoid this if possible.
My question is, if I unlock the bootloader and flash another rom such as from another network or a generic rom, will this unlock the phone so it can be used on other carriers?
Please note the phone currently works on EE, and has not been blacklisted.
Thanks
You cant unlock without box or unlock code
