i just looked on HoFo and pageplus mms uses the same server settings as verizon. So, all you need to do is change the arcsoft server settings (see below) on your phone from alltel to verizon and it will work. Oh...and you have to have data working in case you didn't know. you also have to make sure MMS is enabled on your acct. Call them to have it enabled. Send me an instant message or PM if you need more help.
