$400 T-Mobile Gift Card with Switch!

T-Mobile is offering a highly attractive $400 virtual prepaid Mastercard when you port your number over from a competitor. This deal is available through their latest promotion, which stacks with their existing Keep & Switch rebate of up to $800, making it a very strong incentive to switch carriers.

The deal is especially compelling if you subscribe to their Essentials plan for $100/month per line, or the 4-line plan at $170/month, which effectively provides a significant amount of free service — up to 8-9 months for some users. Additionally, there’s potential to combine this promotion with existing offers like Costco's deal, which could enhance the overall value.

It's worth noting that this promotion is recent, and the $400 rebate plus the stacking options make it one of the best switching incentives we've seen recently. This deal not only provides substantial monetary value upfront but also offers ongoing service savings, making it highly alert-worthy for anyone considering switching carriers.
