I havnt tried, by looking at others' posts, I think it will not work
This is an absolute malpractice and fleecing of customers. Telcos just take advantage of ambiguous and loose laws/guidelines by TRAI / DoT in our country. No one ever thought of explicitly mentioning what all services a telco is "obliged" to provide always. Eg: Voice Call, SMS, Data, MMS.
Blocking Outgoing SMS for lower value packs is unfair trade practice, and yes, it is obvious that they are doing so to prevent users from porting. So, Minimum Recharge for Outgoing SMS is .... what? Like Rs 128 now? And this Rs 128 plan gives ZERO benefits (Rs 0 talktime, 0MB Data). So you may consider that Rs 128 is a "porting fee" - whereas TRAI Clearly mandates that there should be no porting fees for users.
Such is the state of telcos in our country and they are operating hand-in-glove with authorities / government, while the customer keeps suffering.
Also, to make matters worse, Rs 128 plan is no longer available in Vi. So for outgoing SMS, I think the minimum recharge amount would now be the Rs 179 Unlimited Plan. Yet another blow!
