Why Your Travel eSIM Won’t Work in a Router — and What Will

If you've ever tried to put a travel eSIM into a portable router so the whole family (or the whole car) can share one connection, there's a good chance it simply didn't work — and it's not something you did wrong.

Why most travel eSIMs are phone-only

Most travel eSIM apps sell you a data plan tied to an eSIM profile that's designed to be installed on one phone, through that provider's own app. That works well for a single traveller with a single phone — but it runs into two real limits:

• Many travel eSIM plans explicitly don't support hotspotting or tethering — even though the eSIM itself is installed and working, sharing that connection with another device isn't part of what you've bought.
• Most "eSIM-enabled" routers only work with that router maker's own plans — buying a router with eSIM built in doesn't mean you can drop in any travel eSIM you like; it's usually locked to one ecosystem.

Neither of these is a fault in the router or the eSIM — it's just what the product was built for. A travel eSIM app is built to connect one phone, not to be portable across devices.

Why a physical SIM doesn't have this problem

IQ Go is a physical SIM card, not an app-based eSIM profile. That one difference is what makes it work in a phone, a tablet, a portable router or a MiFi device — because a physical SIM doesn't carry the same device-and-app restrictions that a phone-only eSIM plan does. Put it in your phone for a solo trip, or put it in a router and share one connection across a family or a group, without switching products or providers depending on which device you're using.

What that actually looks like

• Travelling as a family? One IQ Go SIM in a portable router covers everyone's phones and tablets over WiFi, rather than everyone needing their own eSIM and their own data allowance.
• Working from a router while you travel? Put the SIM in a router at your accommodation for a stable connection, rather than relying on your phone's hotspot and burning its battery.
• Switching between a phone and a router trip to trip? Same SIM, same £20/year, works in either.

Price: £20 upfront, £20/year to keep it active. Data across 60+ countries, on the EE network, with no monthly bills or roaming surprises.

Frequently asked questions

Why doesn't my travel eSIM work when I put it in a router? Most travel eSIM plans are built for a single phone and don't support sharing the connection with other devices (hotspotting or tethering) — so even if the eSIM installs, sharing it onward often isn't part of what the plan allows.

Does IQ Go work in a normal portable router? Yes — IQ Go is a physical SIM, so it works in any unlocked router or MiFi device, as well as phones and tablets, without being tied to one device or app.

Is IQ Go an eSIM or a physical SIM? A physical SIM card, on the EE network. That's what lets it move freely between a phone and a router, rather than being locked to one device.

How much data do I get with IQ Go? IQ Go is £20 upfront and £20/year to renew, with data across 60+ countries — manage usage and top up any time at my.helloiq.uk.
