Upgrading your SIM.
If you’re on one of our 1 month SIM plans, you can upgrade to a
package with a device after you've been with us for three consecutive
months. We just need to do one more credit check first.
If you’re on one of our 12 month SIM plans, you don’t need to wait until
your contract ends, you can upgrade in the last 30 days of your contract.
