Frequent Asked Questions
  • Which provider has the best Sim Only contract?

    That depends entirely on what's important to you. Are you looking for the lowest price, the fastest 5G connection, or a flexible plan? With Welcompare, you can find the Sim Only contract that best suits your usage and preferences in just a few clicks. You can compare price, speed, contract duration, and more – and our smart AI helps you choose without any hassle. That way, you can be sure you're getting the best deal for you. 

  • Can I also use my Sim Only for business purposes?

    Yes, you can use a Sim Only contract for business purposes. Many providers offer a choice between private and business variants. Important advantages for companies include tax-deductible costs, a VAT invoice, central management of contracts, and often special business services, such as a helpdesk and flexible contracts. Compare easily at Welcompare to find the right bundle for your business use. 

  • What is the difference between prepaid and Sim Only?

    With prepaid, you pay in advance for call minutes, text messages, and data. If your credit runs out, you first have to add more. Sim Only works with a contract that you pay for monthly: you pay afterwards and usually get more in your bundle for less money. Prepaid is useful if you don't use your phone much, while Sim Only is more affordable for regular use. 

  • What is the difference between a Sim Only contract and a mobile contract?

    With a Sim Only contract, you only pay for your calling, texting, and data bundle. You use your own phone or purchase one separately. A mobile contract includes a device, which means you pay extra each month to pay off your smartphone. With Sim Only, you often have lower monthly costs and more flexibility. 

  • What is the cheapest Sim Only contract?

    The cheapest Sim Only contract is usually a bundle with limited data and calling minutes – you only pay for what you use. Providers without their own network can often offer more competitive prices. However, be careful not to choose too little data, because paying extra for additional MB's often costs more. The cheapest contract therefore varies from person to person, depending on your usage. Let Welcompare help you by providing customized advice that perfectly matches you usage.
