Why Choose an eSIM for Your UK Trip?

Traveling with an eSIM offers numerous advantages over traditional physical SIM cards:

• Convenience: No need to search for a local store or stand in line to get a SIM card.
• Flexibility: Change your plan or provider as needed without swapping SIM cards.

• Data Speed Caps: Some plans have a cap on the speed of your data connection after reaching a certain amount of data.
• Fair Usage Policy (FUP): This is the policy that dictates how much data you can use before your speed is throttled or your plan renews.
• Hotspot Restrictions: Some plans may restrict or not support the use of your eSIM as a hotspot.
