hi Lara, If you choose to go ahead with "GOMONTHLY" promotion, your plan will be switched from prepaid to monthly (postpaid). All of your existing prepaid boosters will be lost. Postpaid plan is very different from prepaid though.
there was some discussion here about having to pay for another sim card when switching to postpaid. The suggestion was that one should go to a store to switch, to avoid the sim card fee. However, the store I went into said there's no way to avoid this. Is that the case?
