Walmart right now has a sale on a 3 month SIM package that gives unlimited US calling/text and 5GB of data for $15 (normally $45). A similar package with 15GB is ten dollars more.

A friend was in from Germany, and we picked one up at a local Los Angeles store about 4 days ago. The SIM was coded to work on the T-Mobile network.

He tried to get it running on a circa 2019 Motorola One phone, but Boost indicated it wasn't a supported device once we saw that it was having trouble holding a connection. He switched the SIM to ancient iPhone 6S that his niece had laying around, and it works well (albeit only 4G on that phone of course).

The card he received reflects it expires in May 2024.
