Question?
Answer

Can I get unlimited Sim Only data at Simyo?

We don’t offer unlimited data for Sim Only. Our largest bundle is 20 GB, which should be plenty for most users. Use KPN internet at home? Activate Simyo Compleet to increase your bundle to 30 GB at no extra cost. It's not unlimited, but pretty close.

Prepaid user? You can get unlimited mobile internet with our low-speed Prepaid Unlimited MBs bundle. Great if you want to stay connected, but don’t stream videos. WhatsApp works fine!

How fast is Simyo’s mobile data?

With 5G you’ll enjoy fast and stable speeds, up to 300 Mbps download and 150 Mbps upload speeds.

Will my mobile data stop when I reach my limit?

Only if you set a data limit . This stops your connection as soon as your bundle runs out. Note: the Simyo data limit works only within the Netherlands and the EU (zone 1). Your bundle refreshes on the 1st of each month.

How do I set a data limit?

It’s easy in Mijn Simyo . The limit takes effect on the 1st of the next month. It costs just € 0.50 per month. Once you hit your limit, your connection stops. The limit only works in the Netherlands and EU zone 1.

Can I use Sim Only data with eSIM?

Absolutely! If your phone supports eSIM, you can choose it when you're placing your order. Already a Simyo user? Just switch to eSIM in the Mijn Simyo app .

Can I get a family plan?
