I was skeptical at the beginning and wondered whether it'd actually work. It works very well and I was able to use other SIM cards in my UK phone while travelling in Africa, BUT mind you there is an extra charge on top of the one they initially advertise. First they charge you to check whether it can be done on your phone, then they charge you to complete the entire job.

Deliberately misleading website & process, then overcharges & refuses to refund anything. Avoid!

THEY ARE THIEVES.
They cheat people and steal their money.

No they're not. They run a scam business misleading the customers.
