Which bundle fits you best?

It’s important to think carefully about your data usage. Social media apps like TikTok and Instagram consume more data than just sending a message or an email.

Once you know how much data you need, it’s smart to choose a slightly larger bundle or activate the data cap to avoid additional costs.

FAQ - We've got answers

Can I keep my phone number when switching to Simyo?

Of course. You can request number transfer during the order process. We’ll handle everything with your old provider, completely free. Once approved, your old subscription will be canceled automatically.

You can request number transfer at any time. If you cancel your contract early, your old provider may charge an early termination fee for the remaining months. From 120 days before your contract ends, we’ll automatically make sure your number transfer takes place at the right moment.

Can I use eSIM with my Sim Only subscription?

Yes, eSIM is available for all Simyo customers. Whether you already have a Sim Only subscription or a prepaid SIM card, eSIM is an option. Many phones already support eSIM, but not all, check here first if your device is compatible. If it is, you can activate your eSIM right away.

How does my Sim Only plan work abroad?

Within Europe ( zone 1 ), calling, sending text messages, and mobile data are all included in your Sim Only bundle. You won’t pay any extra fees in all EU countries, plus the UK, Switzerland, Andorra, Norway, Iceland, Monaco, and Liechtenstein.

Are you traveling outside Europe ( zone 1 )? Then your usage is not included in your bundle, and different rates per zone apply.

How can I adjust my Sim Only bundles?

You’re never tied to your bundle. Every month, you can log in to Mijn Simyo and adjust your bundles. Your new bundle starts automatically from the first day of the next month.
