From our experience O2 is the best provider in the UK if you are using a smartphone, due to their data plans (Bonus 500MB when you recharge GBP10 or more and you can purchase another 1GB for GBP9). You can also use skype and do tethering with a laptop or tablet. Coverage is good through most of UK. almost 8 years ago
I am going to Barcelona soon. Where can I get prepaid sim-card with 3G for Internet access? Can I get it from the airport?
The best provider we have found for Internet in Spain is Vodafone (Pepephone use Vodafones network). They have good coverage and a range of data plans (They have an 'unlimited' plan for EUR3.5/week but it is throttled back to 128kbps after the first 20MB each day). If you live in Australia we can send you a SIM before you depart. almost 8 years ago
