Going to Mexico next month for vacation at a resort. The resort has free WIFI. Taking my Droid X so I can check my email. If I put the Droid X in airplane mode and only activate the WIFI will I NOT incurr charges on my Verizon bill. Basically I want to use the Droid X as a computer with no penalty from Verizon for roaming in a foreign country. I don't want to tether - I just want to send and receive emails and use the web. Forgive me if this is too basic of a question. Thanks.
