Why are these carriers recommended?
I have reviewed 30 alternative carriers and over 100 prepaid phone plans, so you don't have to.
To save you time, I have excluded carriers that:
- Only offer unlimited data plans
- Only advertise multi-line prices
- Have confusing phone bills with unexpected fees
- Lure customers with "free" phones
- Constantly try to upsell additional lines
- Bundle plans with unnecessary subscriptions
- Need loads of small print to explain their offers
- Want you to go to a store
- Need a commission-based salesperson
- Reward customer loyalty with increased prices
