This differs per product:
- The Octalarm-Touch, the Octalarm-Touch Pro and SV-product line are delivered with an unactivated SIM card of Wireless Logic Benelux.
- For the Octalarm-Touch and the Octalarm-Touch Pro the SIM card is activated by purchasing Octalarm Connect (€ 13,95 excl. VAT per month). You enter into an agreement with Adésys and pays the amount due directly. Read more about why you should choose Octalarm Connect. This information sheet also explains how to activate the SIM card.
- With the SV product line you enter into an agreement with Wireless Logic Benelux. Several subscriptions are offered. Read more about these subscriptions and how to activate the SIM card.
- The Octalarm-IP with GSM module is supplied without SIM card.
The use of prepaid SIM cards in GSM alarm diallers is strongly discouraged. The equipment is not suitable for checking or topping up the balance (read: credit) of the SIM card. If the balance is missing, the alarm stops, which may lead to damage. In addition, the functionality of a prepaid SIM card is more limited than with a subscription form.
CSD is an analogue dial-up technology on GSM networks and has been used in the M2M world for a long time. However, the newer IP technology has made CSD obsolete. Maintaining the complex CSD network technology no longer fits in the strategy of telecom providers and is therefore being phased out.
What does this mean for you?
As of 01.04.2021 this technique is no longer supported and devices in the data transmission field will have lost their connection with the network. It is therefore important to replace all hardware in time with IP-based solutions.

GSM modems with KPN SIM cards that transfer data over the 2G network via dialled connections will no longer function as of 1 April 2021. Examples of such GSM modems are:
- Severa GSM modems
- Siemens TC35T
- GSM versions of Octalarm-T and Octalarm-IP alarm detectors for pagers
When data transfer is still required, such modems should be replaced by GSM modems and alarm detectors with internet-based data transfer based on GPRS, 3G or 4G. Because the 2G and 3G networks are also switched off, 4G modems are preferred.
Telecom providers started phasing out the 3G network at the beginning of 2020. If your operator no longer supports this network, our alarms will automatically switch back to 2G. However, KPN's 2G network will also be discontinued in April 2025. This limits the life span of older type detectors and they need to be replaced in 5 years at the latest (possibly early) in order not to compromise the safety of your highly critical processes.
Read more about the consequences of switching off the 2G/3G network.
Only older types of detectors that cannot transfer to the 4G network will be affected.

In order not to jeopardise safety in (very critical) processes, we recommend replacing old devices in good time with a newer type that alarms via today's (much changed) digital telephone networks.
