My phone fell into the sink...I dried it out....switched it on and the screen said" contact service"

[dalyer]

Is that the full verbatim message or does it say something else?

You seem to be using a Motorola phone? If so then "Contact service provider" can mean that the phone is locked or cannot use the inserted SIM. If it was previously working OK then perhaps the SIM got damaged and you need a replacement?

Hope this helps.
