MNP (Mobile Number Portability)
Mobile Number Portability is an inter-operator process (usually imposed by country regulators) to allow mobile subscribers to retain their mobile number when switching from one mobile operator to another. For the vast majority of routes, CLX Communications is able to do a lookup from a database or HLR to determine their Home Network and route the message through to the appropriate operator to successfully delivery the message.
Currently 68 countries (out of 196) support MNP, for more information on exactly which countries support MNP see the Mobile Number Portability Wikipedia article (which CLX Communications contributes to from time to time).
