If you like to text friends and family overseas, you know that it can be expensive -- US carriers frequently charge either per text or for blocks of messages that aren't always enough. Pricing won't be a problem if you sign up for Verizon's new World Messaging Unlimited plan, though. As the name implies, the $5 add-on lets you send as many messages as you like to most countries. It also drops the per-minute voice rates to a penny when calling Canada or Mexico, and 5 cents for the rest of the Americas. Verizon describes the unlimited plan as a promotional offer; while there isn't a clear expiry date, we'd suggest acting quickly if you want to chat with the rest of the planet.
