•  About InternationalSIM:
• • Who are we?

  • We are InternationalSIM, a provider of international data solutions. We offer SIM cards that you can arrange before traveling abroad, allowing you to save on roaming costs. With our SIM cards, you won't have to search for cheap SIM cards during your stay overseas. We ensure that your communication needs are taken care of before you depart for your international trip.

  • What is a data SIM card?

  • A data-only SIM card is a SIM card that allows users to use mobile internet on their device but does not include minutes for calling or texting. With a data-only SIM card, users can still make calls or send messages through applications like Skype, WhatsApp, Facebook Messenger, Viber, WeChat, and so on.

  • How does a Roaming SIM card work?

  • Mobile operators establish roaming agreements with other networks, so if your SIM card's home network is not available, it can connect to another mobile network operator. This roaming feature is especially useful when traveling abroad and needing to connect to the internet through mobile data. However, roaming costs are often expensive. A more practical and convenient way to stay connected to the internet while traveling is by purchasing an international SIM card such as one from InternationalSIM.

•  Orders, Payments & Delivery:
• • How fast will my SIM card be delivered?

  • The SIM cards and/or hotspots are shipped within 24 hours on business days from the moment we receive your order. The delivery time depends on the destination.

  • How do I track my order?

  • After placing your order, you will receive an email with a tracking number and a link to the company responsible for delivering your shipment.

  • Why don't you offer free shipping?

  • We do not offer free shipping because the costs incurred for shipping need to be paid somehow. Many online stores incorporate these costs by including them as a markup in the selling price of the products.

•  Compatibility:
• • Can I use a data-only SIM card in my phone?

  • Yes, data-only SIM cards work in any smartphone. While you cannot make standard voice calls and send SMS messages from a phone number associated with a data-only SIM card, internet-based messaging services (such as WhatsApp and Facebook Messenger) and internet calling apps (like Skype and Viber) are practical alternatives.

  • Can I use your SIM card in a MiFi/4G router?

  • Yes, you can use our SIM cards with a MiFi/4G router. Please note that European MiFi/4G routers may not work everywhere in the world, as providers outside Europe use different network frequencies. Therefore, it is important to check whether your MiFi is compatible with the country you are traveling to.

  • Is using tethering via a personal hotspot allowed?

  • Most SIM cards allow this. If there are any restrictions, they will be indicated in the FAQ on the respective product page.

•  Rates & Coverage:
• • What are the costs of a SIM card?

  • All prices of the SIM cards (including any data/call bundles) can be found on our product page.

  • Does my credit expire?

  • When you purchase a SIM card, the validity of the initial credit/first data plan on the SIM card begins only when you establish your first internet connection. This means that as long as you do not use the SIM card, the credit or bundle will not expire. For most SIM cards, the bundle is valid for 30 days. If a bundle has a longer validity period, it will be indicated on the respective product page.

  • Are there any hidden costs?

  • All SIM cards are prepaid. There are no hidden costs, no contracts, no obligations when you purchase any of our SIM cards.

•  IoT and M2M:
• • What is a M2M Sim card?

  • With M2M (machine to machine), it is possible to remotely connect installations, equipment, and sensors through secure multinetwork M2M SIM cards. InternationalSIM offers various solutions combined with flexible contracts. We provide M2M solutions for both low and high data usage. The M2M SIM cards roam on the strongest network available in the EU, UK, and USA. Our SIM cards are suitable for all applications.

  • What kind of bundles do you offer for the M2M SIM card?

  • We offer bundles ranging from 1MB to 100GB.

  • Pooled Data

  • 'Pooled' data is the ability to share data between SIM cards. The unused data from a low-usage SIM card is transferred to a high-usage SIM card. This way, data is first consumed from all bundles. Data does not roll over to the next month.

•  Troubleshooting:
• • I can't connect to the internet, what should I do?

  • If you can't connect to the internet, first check: 1: If you have correctly configured the APN settings. 2: If roaming is enabled on your device. 3 If your SIM card still has (data) credit. 4: if signal bars are displayed on your device's screen.
