A quick comparison of the four UK mobile phone operators show that Three UK currently has the best iPad 2 contract in the country by giving users much more than what the competition is offering.
With O2 having ruled itself out of the market, all carriers chose to compete on features and data allowance rather than on price. This is why all of them offer the iPad 2 16GB at £229 for new customers and £199 for existing ones (for Orange, T-Mobile and Three UK).
T-Mobile has the worst iPad 2 package since you don't get Wi-Fi and still end up paying £25 per month for 1GB anytime + 1GB quiet time traffic. Orange, which uses the same network and should in theory offer the same quality of service, includes 10GB BT Openzone Wi-Fi traffic for the same price.
Vodafone, on the other hand, offers all its package from £27 a month with 2GB anytime data allowance and 1GB BT Openzone Wi-Fi; the operator offers specific iPad 2 deals for its customers but only instore.
They all do compare quite poorly with what Three UK offers though; at 15GB per month, the data allowance of the smallest mobile operator of the country is at least seven times more than its nearest competitor on pure 3G and even surpasses Orange's combined 12 GB 3G & Wi-Fi package.
