How do SIM only plans with no contract work?

With most providers, SIM only plans with a 30-day contract are also referred to as SIM only with no contract, which means you are generally still tied to the agreement for a month even if you sign up for a ‘non-binding’ plan. It is, however, a significantly more flexible option than contracts tied for between 12 and 36 months. You can also view that month as a trial period to determine if the subscription suits your needs and preferences, or if you should switch to another plan or even change provider.

If you wish to continue with the subscription after these 30 days, you are free to do so for as long as you accept the same terms, and the agreement will simply continue until you decide to cancel or switch.

How long can a SIM only contract last?

SIM only plans can have a 12, 18, 24 or 36-month contract, but the periods vary between different providers. Currently, 30 days, 12 and 24 months seem to be the most common contract durations for SIM only plans.

Does a no contract SIM only plan have any notice period?

Yes, almost all SIM only plans have a notice period of 30 days. If you wish to switch to another provider, you must inform your current provider that you wish to terminate the contract at least 30 days before the actual switch takes place. This applies whether your SIM only has a contract or not.

The difference between contract and notice period

  • The contract period refers to the time you are tied to the provider according to the agreement. You must pay the monthly fee for the SIM only plan throughout the entire period, and you cannot switch plan or provider whenever you wish.
  • Notice period refers to the time it takes from when you cancel the SIM only contract to when it is terminated. If the notice period is one month (which it is with most providers), the contract does not end immediately when you cancel it, but continues for another month afterwards.
