Our work is not done just with installing an alarm system for our customers. We are also responsible for maintaining a stable and secure connection for these systems to be immediately informed of incidents in the event of an emergency,” states Claus-Dieter Büttner, Managing Director of C.D. Büttner Security Technology GmbH. “This was not always easy. For example, in new buildings made of reinforced concrete, the reception may be restricted.  Especially if you only use SIM cards from one specific mobile operator as we did before we discovered wherever SIM. If this particular provider had no network at a location, it became cumbersome. In this case, we were only able to secure the connection for our systems via newly installed lines and additionally installed antennas. That was a costly extra effort.

An effort, which is meanwhile a thing of the past. With wherever SIM, Büttner now relies on one SIM card, which always connects to the best mobile network available. If a provider only has poor coverage at one location, the SIM automatically switches to the next best network. Thus, the connection remains stable and the risk of disconnection is minimized.

Since the switchover from ISDN to IP, it is even more important that we have a functioning mobile communications connection. In case of a power failure, the Internet router is no longer supplied with power and the primary connection path is cut. In this case the mobile network must be available, otherwise we lose the connection to the system. We almost eliminated the risk with the use of wherever SIM. “

However, Büttner was not only convinced by the reliability of the connection. “Another plus of wherever SIM is the customer portal. We can see all SIM cards in use at a glance and can easily evaluate all data. This considerably reduces the administrative burden.
