Today 125 euro cashback on SIM only

Belsimpel is running a special promotion today. You get 125 euro cashback if you take out a SIM only from Simyo with at least 10GB data. This offer is only valid today, Monday.
The cashback makes the subscription a lot cheaper. For the cheapest subscription with 10GB data you normally pay 8 euros per month. With the cashback added, you end up with 2.79 euros per month.
NB: the offer is only valid today, on Monday February 23, 2026. Don’t forget to request your cashback after your order.
This is how the calculation works
The calculation is simple. You take out the subscription for 24 months and then request the cashback:
- 24 months x 8 euros = 192 euros total
- 192 euros minus 125 euros cashback = 67 euros
- 67 euros divided by 24 months = 2.79 euros per month
Do you need more data on your iPhone? Then there are also bundles with more data available. For all bundles from 15GB, you also pay 7 euros per month for the first few months instead of the normal price. All bundles receive the 125 euro cashback, making them considerably cheaper:
- 10GB for 2.79 euros per month (normally 8 euros)
- 15GB for 3.29 euros per month (normally 9 euros)
- 20GB for 4.79 euros per month (normally 11 euros)
- 30GB for 6.29 euros per month (normally 13 euros)
