The sale has been closed with Tbaytel for mobility services in Dryden.
City manager Joe van Koeverden says they will start work on transitioning customers on Monday.
He adds letters are being mailed out to residents.
Some people will be mailed new sim cards that they can put in their phones, but some people will have to go to a Tbaytel counter to have their phone switched over.
Van Koeverden says it will take a couple months to get everyone switched over and the process should be complete by mid-December.
