Re: Changing SIM card when changing countries

Are you european ?
In UE carriers have an agreement for international roaming (with fixed prices for something like SMS), so your spanish SIM will work just fine in France (or Italy, or Germany....).
The problem is the price for calls and data usage, quite high under roaming. It depends by the carrier.
If you are going to stay for a while in a foreign country, the best option is a local SIM, unless you have a very good deal for roaming usage with your carrier.

Do you need to have your phone unlocked to use a different carrier sim card? (non-euro phone)...
