    When I bought 2 of them from best buy in Redding CA, I went to use them a few days later and they were expired, one from 2022 and one from 2024. I purchased both in June 2025. The manager, Daria, was very helpful in processing the odd return and attempted to find use replacements. But it turns out the company doesn't seem to do them at all anymore. They only have the options that come with a month of service at the time too, which is fine. But they had had 3 more expired old sim card starter kits on the shelf we went through to see if any would work. Why were so may products that should have been returned to their manufacturer long before hand still on the shelf? The oldest was the one that had expired in 2022, that's a long time to still be on a shelf for sale.

    This was a really great idea to use this temporary SIM. I’m removing one star for the coverage dropouts, though that might not be unusual for other carriers.
