First, Amp'd operates its service through Verizon's network, which is
CDMA. The Z610i uses
GSM.
CDMA and
GSM are both digital wireless technologies, but incompatible with each other. The Z610i will not work on Amp'd. The only way for you to use the Z610i is on a
GSM service. You didn't specify which Amp'd service you are on - US or Canada - but if you're in the US, get an account with either T-Mobile or Cingular since they are the two main
GSM providers. If you can use a smaller/regional
GSM provider like SunCom, then go ahead. If you're in Canada, Rogers/Fido will do.
Second, I don't really keep up with the current news specically with Amp'd Mobile. But it seems that it's going through a bit of a mess right now, considering it's going through Chapter 11 bankruptcy. Probably the reason why you can't get in touch with a rep is because CS and all kinds of customer care have been cut. Amp'd offers a few good deals when compared to Verizon. But I've read about how sometimes the network would just fail, leaving some consumers with no service at extended times.
So, basically you have three choices.
1) Stay with Amp'd Mobile and just use the phones that it offers
2) Terminate your account with Amp'd and sign on with a
GSM provider if you want to use the Z610i.
3) Keep your Amp'd account
& get a new account with a
GSM provider, whether it be pre paid or post paid.
The choice is yours.
