Hello. I have a 8830 Worldphone on Sprint and will be soon traveling to Germany and Canada. What is the cheapest way to talk Internationally? Could I buy a cheap pre-paid SIM card in either of these countries? And if so, will I need to use a different phone number? And how do I set this up on my phone?

Thanks.

The 8830 is a CDMA version with 900/1800 Mhz bands GSM for 'world" travel, however North America uses 850/1900 for GSM. This means the 8830 can be used in GSM mode in Europe, but not in North America- Canada and USA.

If in Canada, your only choice is to use Sprint on the CDMA band. You will pay roaming charges etc.

If in Europe, you can buy a SIM card from any European carrier (with a European number). According to the Sprint website, the GSM SIM is "unlocked". Not sure if you can use your phone with your Sprint account and number, while in Europe. A Sprint 8830 user would have to chime in.

If you had a 8820 BB - this is a quad band GSM version, so if unlocked, you could buy a Canadian SIM card from Rogers while in Canada. Again you would have a different tel. number. Not sure this would make much sense unless you were going to be in Canada for a long time.
