# Swapping Myndr Switch(es)

In May 2025, all switches must be swapped for new ones. From 1 June 2025 the old switches will no longer work. (You can of course always change the mode of the switch in the dashboard.)

**Swapping switches: here's how**
On the back of every switch in your school is a 4-digit code. In the course of May 2025 you will receive a package with new switches. The new switches have the same code. Match the old and the new switch when you swap them. The only thing you need to do to activate the swap is put batteries in the new switch. That way the exchange goes exactly right. Proceed as follows:

1. Take an old switch off the wall plate.
1. Check the code on the back and take the new switch with the same code.
1. Put batteries in the new switch and hang it on the wall plate.
1. After about ten minutes the new switch will work.
1. Do this for every switch at your school.

When you have finished the swap, send the old switches back in the shipping box in which you received the new ones. Seal it well, stick the enclosed return label over the address label and hand the package in at the nearest PostNL point by 30 June 2025 at the latest.

**Swap before 1 June and help a school-age child growing up in poverty**
We understand that you are not exactly looking forward to this extra task. That is why we donate, on your behalf, one euro to Het Jeugdeducatiefonds for every switch you replace before 1 June 2025. Together with all the other IT administrators you will collect a considerable amount and make a difference for children growing up in poverty.

**Why do the switches need to be swapped?**
We developed the Myndr Switch in collaboration with what was then T-Mobile Netherlands. T-Mobile was sold by Deutsche Telekom and became Odido. The IoT department was not part of the sale; Deutsche Telekom wanted to keep it.
However, the agreements between Deutsche Telekom and the new owner of Odido state that Deutsche Telekom may no longer do business with Dutch companies on the telecom market.
That is why we had to look for a new party to supply IoT services. An additional drawback is that all IoT SIM cards supplied by T-Mobile will no longer work after May 2025. That is why all switches must be exchanged. A huge logistical operation that we at Myndr are all working very hard on, also to make it as easy as possible for you!
