I didn't know the the OWU data allowance would expire! I had it for 18 months without issue. Just ported to O2 with their 600 minutes, 1000 texts, and unlimited data bolt-on for £35.

For some reason I was under the impression Orange's 3G coverage is superior to O2's. So not wanting to take a risk, before porting my number, I took out a contract with O2 to test the network. To my surprise over a 6 day period, O2's 3G was superior to that of Orange in EVERY area I checked.

So I returned the phone under the distance selling rule, and ported over my Orange number. Now I'm a happy bunny with my Orbit 2.
