Let’s get started with setting up your device’s SIM tray so you can enjoy fast, on‑the‑go access.

Why Mobile Broadband Matters for Your Flex 5

Many modern laptops come with the capability to use a SIM card for direct internet access. The Lenovo Flex 5, when equipped with a WWAN (Wireless Wide Area Network) module, transforms into a hotspot-ready machine that lets you avoid relying on public Wi‑Fi. Whether you’re running Windows 10 or Windows 11, setting up cellular connectivity ensures your device remains online securely, whether in a café, at a park, or traveling abroad.

Understanding Your Lenovo Flex 5’s SIM Tray

Before we go further, it helps to know what components we’re dealing with. The internal SIM tray is a tiny slot located on the side of the laptop—usually near the USB‑C or headphone jack. Inside, you’ll often find a micro‑SIM or nano‑SIM format, depending on the WWAN card. Lenovo’s documentation also refers to the cellular expansion as the “WWAN slot,” backed by hardware like the Qualcomm Snapdragon X55 modem to support LTE or 5G.

Preparing to Insert the SIM Card

 Power Down Your Device

First, shut down your Lenovo Flex 5 completely using the Start menu. This ensures you don’t risk damaging the SIM reader or losing connection configurations stored in the operating system.

Gather Tools

You’ll need either the SIM‑eject tool that shipped with your package or a small paperclip. These help gently eject the SIM tray without scratching the chassis.

 Check SIM Form Factor

Ensure the SIM card from your carrier is the right size (nano or micro). If not, a SIM adapter can convert nano to micro. Also, verify that your plan includes a data-only SIM suitable for laptops—smartphone SIMs may not provide consistent performance.

Inserting the SIM Card into the Lenovo Flex 5

1. Locate the SIM slot – Usually found on the right side of the Lenovo Flex 5 behind a small plate marked with a SIM icon.

2. Insert the eject tool – Apply gentle pressure until the tray pops out.

3. Load the SIM card – Place the card into the tray with the gold contacts facing down. Ensure it fits flush and clicks gently into place.

4. Reinsert the tray – Slide it fully back into the slot until you hear a soft click.

This physical setup readies your device for the next step: software configuration.
