Hi I received an email the other day from T-mobile stating that as a thanks for being with them I could sign up for the family booster for free (usually £5 a month). It states in the e-mail that if I know anyone else on T-mobile I could forward the e-mail to them, so I presume this offer is available to all T-mobile customers.
The booster allows you to text, call and picture message 4 other chosen T-mobile numbers for free! The only slight catch is the person who signs up for the Booster has to be on a Flext, Combi or Solo plan. Also fair usage applies!
See the following link for all the info: http://www.t-mobile.co.uk/services/uk/familyfree/
Offer ends 30/09/2009!!!
