Frequently asked questions

Our support team is also happy to answer any questions you may have by phone, email or WhatsApp.

What is an eSIM?
Accordion Open
Accordion Close

An eSIM (embedded SIM) is a built-in SIM card in your smartphone that replaces your physical SIM card and is digitally activated.

Is my device eSIM compatible?
Accordion Open
Accordion Close

Most newer smartphones and tablets are eSIM compatible. You can find all eSIM-enabled devices over here. The following requirements must also be met: Roaming must be activated on your device and there must be no SIM lock.

Are there any roaming charges?
Accordion Open
Accordion Close

No, with BuddySIM, there are no roaming charges for your main contract.

When will my eSIM be activated?
Accordion Open
Accordion Close

The validity period and data consumption of your eSIM package only start when data roaming is activated on your device and the eSIM connects to the network. The date of the first data consumption is therefore the start of the validity period of 7 or 30 days. If you are planning a trip in the future, you can easily install your BuddySIM beforehand and only activate data roaming when you start your trip.

Am I entering into a contract?
Accordion Open
Accordion Close

No, you have no contractual relationship with your BuddySIM. It is a pure prepaid eSIM whose term ends after 7 or 30 days or as soon as your data volume is used up. So you don't have to cancel anything!

Can I make calls and send texts?
Accordion Open
Accordion Close

The eSIM only allows you to use mobile data. It does not include a local number for receiving or making calls or messages.

Can I still use WhatsApp?
Accordion Open
Accordion Close

Sure, with your BuddySIM eSIM, you can continue using WhatsApp with complete peace of mind. Your WhatsApp number remains the same even if you activate our eSIM. This means that all your chats and contacts are still there and you can make calls via WhatsApp.

Can I recharge data volume later?
Accordion Open
Accordion Close

If you have already bought a BuddySIM and your data volume has been used up, you can easily do it via whatsapp recharge without installing a new eSIM. Just send us a message with the keyword “Top Up”.
