A roaming or multi-network SIM operates on more than one network within its home country.

Our multi-network SIM operates on O2, Vodafone & EE. The SIM will sit on the strongest network and will change if the signal drops. The SIM will not switch over if there is a network issue, only if the signal drops too low.

If you are on our ‘Multi-Network’ tariff then you have a roaming SIM.

Not yet, but this is something we’re looking into for the future!

This could be for a few different reasons:

• The network in your area is having issues.
• The system needs re-booting. Please turn off the power to the system and turn it back on after a few minutes.
• Your Direct Debit is inactive. To re-instate this, please email sims@commtel.io.

Our monthly rolling contracts can be cancelled at any time with 30 days’ notice.

Our EE SIMs are a 12-month contract. This will move over to a rolling contract once the initial 12-month period has ended. You can cancel once the initial 12-month period has ended, or pay the total line rental for the remainder of the period if you would like to terminate the contract early.

Our Annual SIMs are a 12-month contract, paid for upfront. If the contract is not renewed after the 12-month period, your SIM will be ceased and will no longer work. Our team will contact you with a renewal quote 2 months before the end of the 12-month period.

You can submit a request to cancel your contract here.

Yes, the line rental of any existing pay-monthly contracts will be increasing.

For pay-monthly SIMs, the line rental will automatically change to the new price on the date of the increase. As our annual SIMs are paid for upfront, you will be charged the price advertised at the time of signing up.

All of our pay-monthly SIM contracts are set up with a Direct Debit prior to activation.

If you have an annual SIM, this is paid for up-front, for one year, prior to activation and no Direct Debit is required.

There are a couple of reasons why your Direct Debit may be higher than your invoice.

Your Direct Debit will only be taken if it amounts to £5 or more. As the line rental for our rolling contracts are less than £5 per month, if there are minimal call charges for that month, your bill will be taken the following month instead. Therefore, your Direct Debit amount will be for your last two invoices.

If you have recently re-instated your Direct Debit, there may be an outstanding amount due for the period where the Direct Debit was not in place. This will automatically be taken with your next Direct Debit.

This could be because the cost you were given by the engineer didn’t include VAT, or that you are on one of our monthly rolling contracts where the call charges are in addition to the line rental.

If you would like us to look into this for you, please email sims@commtel.io.

The Multi-Network SIM card in your system has been experiencing issues generating DTMF (Dual Tone Multi-Frequency) tones when the intercom system calls you. Our intercoms use DTMF tones to tell the equipment connected to it (usually a gate, barrier or door) what to do, eg, open, hold open or close.

This issue only affected outgoing calls from the intercom; calling into the unit worked as normal. However, we have been advised by our supplier that the issue has now been resolved, so if you’re still experiencing issues, please contact our technical support team on +44(0)1306 710120 (option 1).

The issue was limited to our Multi-Network SIM cards. If you are unsure whether this affects you, please contact your installer for more information.
