hi there was a news item this week on the bbc about a UK telecoms regulator raiding a rogue mobile phone SMS spam operator/ number harvester in manchester area.
i did a quick look up on the number you listed and got this back.
07034 713 569
Section: Personal Numbering, Radiopaging & Mobile numbers
Use: Personal Numbers
Number 07034 713 569 is potentially valid.
Oftel records show that numbers starting 07034 71 are allocated to Telappliant Ltd. Note that due to number portability if an individual number has moved to a different operator this information is not publicly available.
Oftel's last recorded change for this number range was June 2010.
see here for futher info on who is operating with that sub block <Telappliant Ltd>
contact the UK regulator Icstis (now known as phonepayplus)
though martin lewis
dosent think its all upto scratch (it is a quango you know)
heres the complaint web page
was there any warning that the number was a premium rate number and the rate they charge per minute on the web site ????
heres a tip, use a pay as you go sim with topup packages and keep the current ballance on the SIM at about £1-£5 so you wont get stung if you do accidently get hammered by a cloaked/covert premium rate number (also have premium rate number block activated if its an option on the account)
