Whether you’re an acquirer, processor, or acquiring bank, providing your customers with reliable and secure POS terminals is key. Maximizing uptime and lowering the overall TCO relies on selecting the right SIM solution to power your devices.

Select the wrong SIM, and your customers may encounter connectivity problems or a patchwork of complexities – issues that reflect poorly on your business.

In this post, we’ll discuss why choosing a smart multi-carrier SIM will deliver the highest impact for your business. We also offer a downloadable guide on how to choose the right SIM solution for your POS terminals.

Smart Multi-carrier SIMs boost POS device performance

A traditional SIM card is often configured to connect to one telco’s preferred network. If that network goes down, so can the connection. This could result in service disruptions, missed transactions and, ultimately, damage to your brand reputation.

A smart multi-carrier SIM overcomes the limitations of traditional SIMs, maximizing your terminal’s uptime.

What is a smart multi-carrier SIM?

Unlike traditional telco SIMs, a multi-carrier SIM isn’t tied to a single network. A smart multi-carrier SIM not only connects to the best network available, it will automatically switch networks if it detects a service degradation, which helps provide reliable coverage, and ensure that your customers’ transactions go through.

The ability to switch between multiple networks unshackles your customers’ business from the limitations of a telco SIM. This could improve your devices’ reliability, save your customer money and reduce your support burden.
