An expensive wifi lesson (for T-Mobile)
I bought my first blackberry last December and since that time I've had eight - yeah, eight - blackberrys. Six were 8220's the last two are 8320 curves. It now looks like maybe 90% of the problems were caused by improper provisioning of UMA for my phone.
I received my second 8320 on Monday of this week and started having problems yesterday. It would drop the UMA, people could hear me, but I could not hear them. I started getting all kinds of strange error messages and it got so bad I could not use my phone over wifi.
This morning I called T-Mobile blackberry tech support and after getting transferred four or five times I finally get a UMA specialist. It took him about two minutes to say "your UMA provisioning is all wrong - it's no wonder you have been having problems". I told him about the problems I had been having since last December and he said he could not tell if the set-up on T-Mobile's end had ever been changed, but he doubted it had and that was likely the cause of all the problems I was having.
He told me to hang up and pull the battery and when the phone came back up the problems would be gone - said he had already corrected the provisioning. Sure enough after pulling the battery and re-starting the phone it acts like it's fixed. The wifi signals I'm getting now are stronger than they have ever been.
All this time I have been cursing the 8220 for being a POS and all along it was a software error on T-Mobile's part.
