An O2 SIM card in your phone gives you cheap local and international calls from the UK. Its main advantage over other UK SIM cards is the excellent range of bolt-ons that give you internet access, cheap international calls and cheap European roaming.
O2's Pay & Go plans have an add-on option that lets you use data on your phone on a prepaid plan. Although O2's voice charges are slightly higher than our Lebara SIM, the O2 data charges are very good value and the My Europe Extra bolt on makes it an excellent value option for use throughout Europe. Overall an O2 SIM card is an excellent choice if you're visiting the UK and making side trips to Europe.
Call charges are as follows:
- Calls to UK landline and UK mobile phones 30p per minute
- Calls to 0500, 0505, 055, 056, 080 and 082 numbers 15p per minute
- Calls to 07744 and 07755 numbers 25p per minute

Bolt ons are the best bit about O2's Pay & Go plans. These let you pay a bit more in exchange for lower call charges or extra features like unlimited data and low-cost roaming in Europe.
Rather than confuse you with the full list of available bolt ons, we will just list the four most popular ones here.
O2's Web bolt ons let you access the internet from your phone.
The Basics Web bolt on gives you access to 100MB of 3G data for £3 per month. This bolt on is ideal if you only need a little bit of data or if you will only be in the UK for around one week..
The All Rounder Web bolt on gives you access to 500MB of 3G data plus unlimited Wi-Fi access at thousands of BT Openzone and the Cloud Wi-Fi hotspots in the UK on your phone plus 20 MMS picture messages for £6 per month. This includes both 3G data and Wi-Fi access at 7500 BT Openzone and the Cloud Wi-Fi hotspots. This is the most popular Web bolt on and is ideal if you're travelling with a smartphone like the Apple iPhone.
The Works Web bolt on gives you access to 1GB of 3G data plus unlimited Wi-Fi access at thousands of BT Openzone and the Cloud Wi-Fi hotspots on your phone plus 50 MMS picture messages for £10 per month. This includes both 3G data and Wi-Fi access at 7500 BT Openzone and the Cloud Wi-Fi hotspots. This bolt on is ideal if you're travelling with a smartphone like the Apple iPhone and need more data.
To set up O2 Web bolt ons call 2425 free of charge from your Pay & Go mobile phone.
Data is only included with O2's Web bolt-ons in England, Northern Ireland, Scotland and Wales. No data is included when roaming outside the UK.
You are charged £1 per day for data if you don't have a web bolt-on or if you have used all your web bolt-on allowance.
O2 Travel is a new bolt-on that gives you cheaper data while roaming in many European countries. O2 Travel costs £1.99 for 50MB data during one day while travelling in Andorra, Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Monaco, Germany, Gibraltar, Greece, Guernsey, Hungary, Iceland, Ireland, Isle of Man, Italy, Vatican, San Marino, Jersey, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden and Switzerland.
In most cases this bolt-on will already be active on your account, however it is best to call O2 customer service on 4445 prior to leaving the UK to double check this otherwise you may be charged the casual European roaming rate of 19p/MB. You can add the O2 Travel bolt-on by texing TRAVELON to 21300 this feature is not already enabled on your mobile.
When you have used your 50MB daily allowance you can add an additional 50MB by texting MORETRAVEL to 21300.
