Flex Mobile
A prepaid carrier aimed squarely at people who have been turned down elsewhere — no credit check, no deposit, no contract.
Our verdict
Flex Mobile sells to the same person our no-credit-check guide is written for: someone who needs a working line and has been quoted a deposit somewhere else.
Because it is prepaid there is nothing to underwrite, so approval is not the obstacle. What you are trading is network priority and the depth of support you would get from a first-party carrier.
Plans start at $14/mo on T-Mobile's network with eSIM activation, and the brand leans on a membership framing — rewards and travel perks alongside the service itself. That is either a bonus or noise depending on how you shop.
Worth comparing directly against Mint, which sits on the same T-Mobile network with a longer record, and against Visible if Verizon's coverage is stronger where you live.

Frequently asked
Does Flex Mobile require a credit check?
No. It is prepaid, so there is no credit check, no deposit and no contract.
What network does Flex Mobile use?
T-Mobile. Coverage matches T-Mobile's own map, with prepaid traffic deprioritized behind T-Mobile's direct customers when the network is congested.
How much does Flex Mobile cost?
Plans start at $14/mo. Flex sells 3- and 6-month unlimited terms alongside monthly service, and runs promotional discounts on the longer terms — check the term price at checkout rather than the monthly headline.
Can I bring my own phone?
Yes, most recent unlocked handsets are supported, and you can port your existing number.
Is there a deposit?
No. Prepaid billing means you pay before you use the service, so there is nothing to secure with a deposit.
Does Flex Mobile sell home internet?
No. For a home connection, see our prepaid internet and no-credit-check internet guides.
