This phone is compatible with the following audio formats: AAC (MPEG2 & MPEG4), AAC+, eAAC+, AMR (NB), MIDI, SP-Midi, WAV, WMA, MP3, SMAF, XMF , 3ga , m4a.
I ordered a Samsung T199 and Starter Kit on Walmart website, but they canceled my Phone order because they were out of stock. So now I have a Family Plan Starter Kit and Sim card, but no phone. If I buy the Samsung T199 off of best buy, with them both being powered by t-mobile, will they both work together.
I also have family mobile. Wanted the ALCATEL FIERCE 2. Cheaper at best buy because discontinued. Put SIM & SD card in from previous family mobile phone (LG optimus). Both phones compatable with T-MOBILE. All worked out fine. No problems. Hope this helps
