Need a quick top-up for a Sister Mobile line? This $5 prepaid eCard is delivered straight to your email – no waiting for mail, no physical card. It adds 400 minutes of talk time and a small amount of data (less than 1GB) to your account on the T-Mobile network. Super convenient for when you're running low and need service fast. Perfect for a backup phone, a visitor to the US, or a gift. Just a heads up: these cards usually have a shorter expiration date, between 15 to 29 days after purchase, so use it soon after you get it. Brand is Sister Mobile. UPC does not apply. It's a digital product, brand new and unused. A simple, no-fuss way to keep your prepaid phone alive. Get the code, redeem it, and you're back in business.
