My husband and I both have Droid Eris. We've added and activated International Roaming service prior to our arrival in London, UK last night (11/8) from the U.S., and we're told by Verizon Wireless Rep. that we're all set when we got into London. Well, we're disapointed to learn that's NOT the case. We keep getting "NOT REGISTERED ON NETWORK" whenever we attempted to make a call ever since we arrived here in London. We've tried everything that advised in VW's "help" section and nothing works! Has anyone ever experienced the same problem? Solution?
