It has been reported by SMS VAS providers (operators, gateways,
aggregators) that Mobilink is blocking branded SMS/corporate SMS
alerts from other networks to its subscribers. On contact, they were
asked to initiate that traffic from mobilink's own SMSC. It appears to
be linked with the recent campaign from Mobilink and Telenor to impose
interconnect fee of 10 paisa on SMS termination (http://
propakistani.pk/2010/01/15/off-net-calls-and-sms-rates-high/).
Cleverly, they didn't block it on P2P SMS since it may backfire to
their prepaid subscriber base, rather they have started this on
corporate SMS services which may bring some customers or at least
traffic to them. Operators don't have an immediate solution but have
logged a complain at PTA. Gateways and aggregators are routing 030
traffic by initiating it on Mobilink SMSC. The ported numbers are
suffering again specially the numbers ported into mobilink as their
prefix takes them to some other SMSC and when routed to mobilink, it
blocks since it was initiated from someone else.
