Pros and cons

Chattr SIM Only

Pros

  • £5 is the entry price on the SIM only plan, and No price hikes means the renewal bill does not climb
  • included roaming across 43 countries comes as standard rather than as an add-on
  • Rolling billing on a term of 1-month means the line can end without an exit charge

Cons

  • Support runs on email only, so a question with no quick email answer waits for a reply
  • Service covers GB alone, so the SIM does not work for a trip outside the UK unless roaming applies
  • Chattr SIM Only is an mvno on the O2 network, so coverage follows the host rather than a network of its own

Meow Mobile

Pros

  • Entry pricing is easy to start with: the capped data plan starts at $10 a month and the unlimited plan opens at $15.
  • A credit check is not required, so a line can be opened without a credit history being put forward.
  • Billing is prepaid and rolling, so there is no long fixed term to serve out and nothing to negotiate on leaving.

Cons

  • The renewal step is the catch: Initial $15/mo for 3 months then $30/mo, so the opening unlimited figure is not the rate you keep.
  • It serves a single market, US, and roaming is paid, so travel costs sit on top of the monthly bill.
  • Support runs on email and chat only, so there is no phone line for anyone who wants to talk a problem through.

Who each suits

Chattr SIM Only

Who it suits

  • Anyone in GB already holding a handset and happy to bring their own SIM
  • Travellers who want included across 43 countries without a roaming add-on
  • People who need a credit check free line and prefer rolling billing over a locked contract

Who should look elsewhere

  • GETESA, Lonestar Cell MTN and yesss! sell as networks rather than an mvno, so buyers wanting the host's own support and shop presence should look there first
  • Phone buyers wanting a handset bundled with the line, as this offer is SIM only
  • People wanting phone or chat support, since help runs on email alone

Meow Mobile

Who it suits

  • Households in the US that want a prepaid, rolling SIM only line on AT&T without a long contract.
  • People who rarely leave the country and stream or hotspot often, since roaming is paid and unmetered data opens at $15.
  • Anyone adding a spare line for a child, a partner or a second phone, since a credit check is not required and hotspot sharing is included.

Who should look elsewhere

  • GETESA, which sells as a network (network), for readers who want the host network itself rather than a virtual network operator.
  • yesss! and Lonestar Cell MTN, both sold as networks (network, network), for anyone who treats buying direct from the network as a condition rather than a preference.

Questions about each

Chattr SIM Only

What does the cheapest Chattr SIM Only plan cost?+

The SIM only line starts at £5. That is the entry price for the plan rather than a promotional first bill, and No price hikes applies, so the same figure carries over to renewal. Larger data allowances are available on the same rolling billing.

Does the price go up when I renew?+

No. The stated position is No price hikes, so the monthly figure a customer starts on is the figure carried forward. Renewal pricing is therefore predictable, which is unusual among rolling SIM only deals where providers often adjust charges over time.

Meow Mobile

What does Meow Mobile cost to start, and what happens to the price later?+

The capped data plan starts at $10 a month and the unlimited plan opens at $15. The opening unlimited rate is introductory, because Initial $15/mo for 3 months then $30/mo. Budget from the ongoing rate rather than the headline figure, since that step is what most of the monthly bill depends on.

Is Meow Mobile a network or a virtual operator?+

Meow Mobile is a virtual network operator, so the coverage comes from AT&T while the plans, pricing and support are its own. That split is the usual reason a plan here can sit below what the network charges. Readers who prefer to buy from the network itself have GETESA and yesss! listed alongside, both of which sell as networks.
