your line,still can make Long distance calls, but your rate will be the highest rate from Bell (to China, about $3.00/min). Recommend if don't use Bell's long Distance, cancel the saving plan, Save $1.25/mon and when you need make LD calls for emergency, use 1010xxx (Such as 1015945 then LD Number) to make LD call which is cheaper.
The network charge is because the government has just canceled some money supply to all telecommunicating companies on rural communication, including the Cell phone companies. This is why all the cell phone compies increased access fee from about $4/mon to $7/mon. Also Sprint and Primus has the network charge too. However Bell has options, can cancel any Long distance Saving plan. Don't block Long Distance access, cuz when reactivate it, there is $10 charge.
