My nephew is going to Germany in a couple of weeks. I have a roaming SIM which has a US and Germany number and where I can purchase 5gigs of German data for EUR20. I also have a junk TMobile Comet which I unlocked. I was thinking of loaning it to him to both tether and do VOIP Over 3g. The phone is only a 524mhz processor and was wondering whether it is too anemic a phone for the job I am proposing.
