co:sim questions, answered

We have not published any verified co:sim prices yet. We only list a plan once its price has been checked against co:sim's own listing, so the page stays empty rather than showing a guess.

co:sim is operated by co:sim and its service runs on Multi-network. That means the towers you connect to are the host network's towers, so signal in your area follows that network rather than co:sim building its own masts.

Coverage depends on the Multi-network footprint at your address, not on co:sim itself. Use our coverage checker to enter your ZIP and see the filed figures for that network, plus the registered structures nearby. Where a network has not filed data with the FCC we say "not filed yet" rather than estimating it.

We do not have a verified co:sim price to quote yet. As soon as a price is checked against the operator's own listing it appears on the co:sim page.

We have no published data allowances for co:sim yet.

We have not confirmed eSIM support for co:sim, so its plans are listed as physical nano-SIM. If that changes on the operator's own site, the page updates when we next verify it.

The co:sim plans we list are month to month, with no fixed term. We have not recorded an activation fee on the plans currently listed.

In most cases yes. A phone bought unlocked, or unlocked by your previous operator, will work as long as it supports the Multi-network bands. Your number is kept by requesting a port from co:sim during signup — do not cancel your old service first, or the number can be lost.

We have not published a verified price check for co:sim yet, so no price is shown on the page.

Sometimes. If you buy through a link on this site we may earn a commission from the operator or its affiliate network. It never changes the ranking, the prices we show, or which plans appear — those come from the same verified catalogue either way.
