spv c500 abroad

[Guest artyom]

In the summer i'm going to australia, vietnam and thailand, i want to be able to use my spv, mainly to contact friends who will be with me abroad, but also to use to send txt back to the UK, i have unlocked the phone to all networks, and am just looking for advice as to what to do, will my sim work abroad, if so will it be expensive, or should i buy a sim card while i'm abroad to use in the phone?

any help or advice will be much appreciated, thanks

If you have roaming available then you should be ok but that will depend on the country you are in.

If you plan to use the phone a lot then buying a SIM card when you are in the country could be a better option.
