What should I know about using a cellular phone internationally?

Answer 1

Before taking your cell phone internationally, you will want to take some measures to prevent heavy roaming fees: if you have a SIM card based phone, it may be easiest to buy a prepaid phone in the country you are travelling to, and swap the SIMs. Another option is to call your carrier and discuss international/roaming plans, but be warned, these will generally be quite expensive, and may not become effective immediately. Depending on your phone model, you may also want to make sure that your device supports the frequency bands used in the countries you are travelling to.
