If I live in America,how can I call someone in Latvia?

Question

can I text?

and do I need to type in extra numbers?

or what?

Answer 1

You need the international access code to dial out of the US being 011 and the country county for Latvia being +371

So dial 011 371 xxxxxxx (x*x being the local number for Latvia.  If there is a '0' in front of the local number then you take this away (but if I recall this is not the case for Latvia)
