Want to switch from a data plan to Talk & Text

The two paths are separate. Plans with data are one path, and Talk and Text are the other. The simplest path is to call sales, or visit a retail sales point. Alternately, you can move between post-paid and prepaid services, porting your number as part of the process. Given you want to address this on 2 phones, I suggest speaking to a retailer.

Note: while you can port a number from post-paid to prepaid & vice versa, you can’t port between data and  talk/text only plans. You’ll need to involve a rep.
