T-Mobile announced on Thursday that T-Mobile customers trying to connect with “loved ones in Haiti during the aftermath” of the earthquake can now make calls to Haiti without being charged for international long distance calls. Customers who are already in Haiti may also roam in Haiti on T-Mobile’s Partner networks Voila and Digicel and without accruing international roaming charges. The free calls and roaming are retroactive to Jan. 12, and will end on Jan 31. T-Mobile will remove charges from customers’ bills accordingly.

Our company and our employees care deeply for our customers, and we know that many customers have been directly impacted by the disaster in Haiti,” said Robert Dotson, president and CEO, T-Mobile USA. “While our thoughts go out to those in Haiti who are suffering so greatly at this time, our promise is to help people connect with those who matter most. I can think of no better time to demonstrate this commitment.

You will need to have a texting plan on your account to cover any incoming and outgoing text messages. You will still be charged for standard text messaging rates if you do not have a texting plan, or for overages if you go over your existing texting plan. The same also applies for phones calls; you will be charged for overages if you go over your plan limits.

BlackBerry users have additional capability with unlimited instant notification from loved ones via Facebook, Twitter, and Email. Unlike other devices that required 3G services, BlackBerry can perform with just the minimal basic GPRS data service. As basic service is restored, BlackBerry users in Haiti will be able to communicate via BlackBerry Messenger, PIN to PIN and other Instant Messaging Platforms.
