I can make calls over UMA (router) when I am in the US and it only takes away on my minutes. I am going to Jamaica in 2 weeks, and I would like to make US-Bound calls from Jamaica. The hotel that I am staying at has free wifi. I called T-Mobile and asked them, if I am not using regular cellphone band and only using WiFi, can T-Mobile charge me roaming?

I presented the question to T-Mobile and am getting mixed answers... How would they know where I am making the call from if I am making calls via the Internet. Can they trace the IP to Jamaica and realize that I am calling internationally?

I thought about this and also realize that some internet connections in the US have a European IP Address.

I would like to know if anyone else has done this before and if they got charges.

Thanks for your input!
