How are you doing HLR lookups for numbers in vodafone range in the UK? I thought companies were barred from sharing this information? Apparently txtnation is not allowed to do this. Not sure how current this blog post is.
'The UK is an unusual country as far as number portability is concerned. There is no central number administration database, and Vodafone UK prevent HLR Lookups to all parties. Hence, we currently fully resolve all UK mobile numbers except Vodafone ported out. - If you query a Vodafone number our Gateway responds based on number range info. - If the Vodafone number has been ported out, our Gateway response will still come up as a Vodafone number. - If a number has been ported in to Vodafone, our Gateway response will be correct. NOTE: Vodafone UK is only reachable with the NPLU, it is still blocked with RTLU. To be more accurate, it's blocked if the number range belongs to Vodafone.'
