Dual SIM, Multi SIM and eSIM: three different questions

Device dual SIM, an operator multi-SIM service and eSIM are three different questions.

On this page

Device capability vs SIM format vs operator service

Choose an appropriate device and subscription arrangement. Device capability vs SIM format vs operator service is a check you do with the current written offer, the operator account and, where it applies, the official e& or TDRA page. It is not a Probiz price and it does not reserve a number.

The existing eSIM guide does not explain these commonly confused concepts. A labelled device-and-line diagram using one consistent icon set; no unsupported smartwatch entitlement.

Two lines on one phone

Choose an appropriate device and subscription arrangement. Two lines on one phone is a check you do with the current written offer, the operator account and, where it applies, the official e& or TDRA page. It is not a Probiz price and it does not reserve a number.

The existing eSIM guide does not explain these commonly confused concepts. Write down what you were told, who said it, and which plan version it referred to.

One subscription across eligible devices

Choose an appropriate device and subscription arrangement. One subscription across eligible devices is a check you do with the current written offer, the operator account and, where it applies, the official e& or TDRA page. It is not a Probiz price and it does not reserve a number.

The existing eSIM guide does not explain these commonly confused concepts. Write down what you were told, who said it, and which plan version it referred to.

Check plan exclusions

Choose an appropriate device and subscription arrangement. Check plan exclusions is a check you do with the current written offer, the operator account and, where it applies, the official e& or TDRA page. It is not a Probiz price and it does not reserve a number.

The existing eSIM guide does not explain these commonly confused concepts. Write down what you were told, who said it, and which plan version it referred to.

Ask the right compatibility questions

Choose an appropriate device and subscription arrangement. Ask the right compatibility questions is a check you do with the current written offer, the operator account and, where it applies, the official e& or TDRA page. It is not a Probiz price and it does not reserve a number.

The existing eSIM guide does not explain these commonly confused concepts. Write down what you were told, who said it, and which plan version it referred to.

  • Keep the exact number or address and the plan name.
  • Save the accepted quote and any reference number.
  • Ask in website chat if a fact is not on the current listing. Do not treat a shortlist as a hold.

Key takeaway

Choose an appropriate device and subscription arrangement. Confirm figures on the written offer. An enquiry does not reserve a number.
