TMO Wants Sprint Users to Swap Out SIMs TMO wants us Sprint customers to go to our local TMO store and have them swap out our Sprint SIMs for TMO ones for a "better network experience". Has anyone done this with any regrets? I'd like to know before I feel like I'm Indiana Jones walking in the store with blind faith off a cliff that everything will be "better". 2021-Jan-16 9:26 am My friend has sprint still and they have not asked him to swap out sims. Maybe it is to hasten the intergration from the older service that actually worked to to their service that is worse in our neck of the woods
