This UK eSIM (O2) plan will last 30 Days from activation. If you are staying longer than 30 days, you will need to recharge the sim. If you wish to add credit or recharge the sim you can only do this whilst you are in the UK, at O2 stores, supermarkets, petrol stations and convenience stores. Unfortunately, you are unable to top-up online via the O2's website, as it may require a UK debit/credit card that is linked to a UK residential address.

However, we advise that you visit an O2 store when recharging, as this will ensure that the recharge has been done correctly and you have received the most appropriate plan.

Alternatively, as another option if you are travelling for longer than 30 days, you can purchase additional sim cards based on the duration of your travels. If you are travelling for 56 days you can purchase 2 separate sim cards, and then swap them over at the end of each 30 day period.

If someone wishes to call you on your UK number they would need to drop the leading 0 and add the UK calling code of +44 regardless of which country you are in.

For example, if the phone number noted on the pack is 07307452691, they would need to dial +447307452691. (To get the + on a mobile phone, press and hold 0 until it turns into a +)

Please Note: If someone from outside of the UK wishes to call or SMS you directly they would be charged at international rates to a UK number.
