All of a sudden, my phone is not recognized on Sprint/Verizon's system, so I can't roam on their network. It's like they've restricted me to Alltel's towers only, so if there is no Alltel, then my phone will not work, because Sprint/Verizon's system won't recognize my phone. My phone works fine on Alltel's network. I should be able to use Verizon & Sprint's network where I am. (forced roam or not). Only my phone has this problem. This happened once before when I got another new (LG AX4270) phone, but it fixed itself when I programmed Sprint/Verizon SIDs in NAM2. Now this doesn't work. We have 4 LG AX4270 phones. All our other phones will work normally, just not my own. It worked fine for the last 10 months with no trouble, now it doesn't recognize my phone as legit when I want to roam. 11 months ago, I couldn't use Sprint or Verizon on NAM1 while in NJ. The CS reps said to try *228 and options 2 & 3. Nothing worked, my PRL is 20029. Remember, it's only my phone with this unique problem, every other phone works fine on everyone. I think the problem is the ESN. I think I should goto the Alltel store, this way they can look at my ESN, and see if they could make it compatable to roam again. I hope this problem is resolved soon, because if I want to go somewhere with no Alltel, then my phone is as good as a paperweight, and I'll have to use different phone. I get the following error messages instead of successful calls: On Sprint: "Your autherntication code code not be verified, please stay on the line for a customer care representative, message 264-16". On Verizon: "Welcome to Verizon Wireless, we're sorry, we're currently unable to authenticate your phone, please try your call again. If you continue to experience problems, please hang up and dial #8899 from your wireless phone. Announcement 11, switch 139-103."
