Heads up, everyone, the price of T-Mobile’s SIM Starter Kit went up today.

T-Mobile is now charging $25 for the SIM Starter Kit that is included with new activations. The prices of both the postpaid and prepaid SIM Starter Kits have gone up to $25 today, but T-Mo is offering a limited time $15 instant discount on the prepaid SIM Starter Kit.

This price increase comes one year after the last SIM Starter Kit price bump that raised its price to $20. Also, it’s worth noting that today is the start of T-Mobile’s free line promo, so keep this price increase in mind if you’re planning on adding a line and taking advantage of that promo.

Thanks, anon!
