MobileBoost MobileBoost Mobile $365 Pre-Paid SIM Starter Kit

Grab a 365GB Boost Mobile 12-month SIM for $365 and score $70 cashback via TopCashback — that's an effective $235 for a whole year of data, working out to under $20 a month.

  • Just remember to activate your SIM within 30 days of purchase
  • Buying more than one? Make sure each SIM is a separate transaction or your cashback won't track
  • Heads up: cashback doesn't apply to eSIMs, recharges, phones, or purchases made through the Boost app

If you're after a big-data, set-and-forget plan for the year, this one's a solid pick — just follow the conditions and that $70 is yours.
