In the wake of the devastating Nepalese earthquake, many T-Mobile customers are trying to stay in touch with their family and friends in Nepal. T-Mobile is making this easier by waiving and crediting fees for all calls and text messages to and from Nepal from Saturday, April 25 through Saturday, May 16. Calling and texting to and from Nepal without charges applies to all postpaid and prepaid customers of T-Mobile, MetroPCS, GoSmart Mobile and Walmart Family Mobile with international calling.

For those interested in helping immediately, T-Mobile customers can simply text-to-donate in support of the following charities’ Nepalese disaster relief efforts:
Save the Children – Text NEPAL to 20222 to donate $10 to Save the Children
UNICEF – Text NEPAL to 864233 to donate $10 to UNICEF
World Vision – Text NEPAL to 777444 to donate $10 to World Vision
Your donation will be charged to your T-Mobile phone bill, and 100% of this donation goes directly to the charity.
