Frequently Asked Questions

How long does eSIM activation take in London?

Normally, it won't take much more than a few minutes for activation to occur. However, there may be some rare circumstances where activating will take up to 24 hours due to the network environment. If you are at an airport, connect to Wi-Fi in the terminal so that activation will probably happen immediately.

Is it possible to maintain an existing mobile number when activating my new Lyca Mobile eSIM?

Yes, you can transfer your existing mobile number from your current UK provider to your new Lyca Mobile eSIM by requesting a PAC Code (Porting Authorisation Code) from your current provider and providing this to Lyca Mobile when activating your plan.

Can I use an eSIM and a physical SIM at the same time?

Generally, most current model smartphones allow for the use of two SIMs. That means you can use eSIM and physical SIM together at the same time. This is useful when you want to maintain your home country's number while using Lyca Mobile as your local UK data/calling provider.

My eSIM QR code isn't scanning. What should I do?

Try entering this information yourself, go to the settings on your phone to the eSIM feature and select "Manually enter details." You will have needed to have received both the SM-DP+ Address and Activation Code in the welcome email from Lyca Mobile. If you are unable to do this, please contact support.

Is a Lyca Mobile eSIM a good option for tourists visiting London?

You can use Lyca Mobile's PAYG plans if you're a visitor, since they don't require any contracts, have great value data allowances, and require no activation fees. In fact, you'll be able to receive your UK phone number and have data available to use before you leave the airport (for example, at baggage claim).
