I have Altell TP, still have Altell plan, but provider is Verizon. This Rom should be fine for you to try. I use NRGZ on my TP and TankROM on my wife's.
Do the flash dance. Then flash this ROM. Hard reset. When setting up to use do *228, let that finish, soft reset.
Go communications setup enter "phonenumber@vtext.com"
Do the rest of your setup as usual.
You may also, consider changing to a Verizon Radio, I use 1.03.09v
Best of Luck
