Scenerio: Customer comes in and says; "I have FIVE phone lines with TMobile and the Blackberry Unlimited Data Plan since 2002. It's a Family Plan and serves exactly that purpose. Recently we wanted to upgrade to "MyFaves" however, the Blackberry 8700G is not compatible with "MyFaves."
OK: If you came into my store (i am a retail store manager) NOT an Indirect Dealer (person who owns a business and can sell any service provider) & I hope you did not go one. (If you did visit an Indirect Dealer this might explain your dilemma); this is what I would have said to you Hotweelz.
Thanks for being a TMO customer and I reccommend you do change your Family plan to the Fave 5.
1st Question; which Family plan?
2nd Question; everyone has a BB or various handsets?
3rd Question; do any of the 5 persons want to upgrade their handset to a Myfaves handset?
if answer is yes; then do the upgrades 1st.
is answer is no; then just continue with Plan change.
All TMO handsets are now MyFaves, BUT those released before 6/07 are not.
Remember if you unlocked your phone from another carrier, well its not going have the myfaves interface.
YET you can to t-mobile.com and sign up for MyTmobile. Its FREE and it lets you do such things as view your bill, make a payment, download stuff, add a feature etc..etc and manage, assign and/or change your MyFaves numbers.
I have a Samsung t809 my wife has a 1st gen RAZR; NEITHER phone have the myfaves interface;
But we manage our MyFaves through the MyTmobile on t-mobile.com.
Bottom line is: if all lines are BB phones or various phones ,IT DOES NOT MATTER. You are changing PLANS not phones.
Sorry you had to go through all that.
