Would I need to unlock a Vodafone phone for my Talkmobile sim?

[Rebecca R]

I have a talkmobile sim card and was thinking about buying a Vodafone phone from a friend, I was wondering if I would need to unlock the phone or not? I've had phones unlocked before and it's cost about ?15 so its not a big deal, but would just like to know whether or not it would be necessary.
I don't have the phone yet, will probably get it sometime next week, was just wondering about it just now. Know any cheaper methods then?

Yes. If the phone is network locked to Vodafone you need to unlock it. Only the phone will be accessible with other network SIM cards. You can unlock your phone using unlock code. You can get the unlock code from www.Unlocking4u.com at affordable cost with easy unlocking instruction guide. All the best mate.
