Beeline has announced their new dialing prefix 067 a few days ago in advertisements. I have updated the relevant past posts in this blog.
They also announced new prices by sending an SMS to existing Super Zero customers that the plan is being changed to a new plan called Super Plus effective from 2010-02-22. The SMS was sent to the author of this blog on 2010-02-21 at 21:29. The new prices were not mentioned, the SMS asks customers to call 0660 for details.
The Phnom Penh Post also has an article on the pricing change on their 2010-02-23 issue. According to the article the across-network price is $0.06 per minute with the new tariff. The new within-network price is also $0.06 per minute but the customers are being charged only for the two first minutes of a call up to 15 minutes. It is unclear how long this will last.
Update on 2010-02-25: Yesterday Beeline sent an SMS to their new Super Plus plan customers informing that they will get $0.06 added to their balance for every received across-network phone call which lasts more than one minute.
Update on 2010-04-12: Yesterday Beeline sent an SMS to their Super Plus customers informing that they will stop the incoming call bonus effective on 2010-04-12.
