The time has come...
I've been on one of Telstra's old grandfathered plans for a few years now. $39 per month, unlimited data (35GB at full 4G/LTE speeds then shaped after that), unlimited national calls, unlimited national SMS.
From the end of next month, Telstra is forcing all customers on grandfathered plans onto one of their current plans, but with a $20/month discount for the first 12 months as a sweetener. Essentially for me, I just get more data and access to the 5G network for an additional $6/month for the first 12 months.
I don't know how many of you are in the same situation?
