LEMAY, Mo. (AP) — For more than a decade, Missourians have been able to ban most telemarketing calls from their landline phones, a protection that has been extended to cellphones following a bill-signing ceremony on Thursday.

Gov. Jay Nixon was in St. Louis County to sign into law a measure allowing cellphone numbers to be added to the state’s no-call list for telemarketers. The law prohibits most phone solicitations to cellphones placed on the list. It also bans unwanted text and multimedia messages.
