Is it "free roaming" true?

There is indeed a high price you pay when calling +372 numbers and I would advice not to use a card in this number range. some carriers (voip) don't even connect to these numbers.

If you want to buy a card get one that has a +44 number, using voip you can call these numbers for 5 to 6 eurocent / 8 dollarcent per minute.

some card providers also have a fair use rate meaning that if you receive to many calls and not make any calls you will be disconnected. so for example for every 5 incoming calls you have to make 1 outgoing call. They look at this on a monthy, or serval month time frame,

The call rates that some cahrge have setup fee and they really only make money on outgoing calls and this pays for the incoming calls.

So basically stay away from +372 number, go for a +44 number, check the smallprint and if you read fair use, stay away if you expect to receive many incoming calls and not many outgoing calls
