I am on a fairly ordinary $20 / month plan with Woolworths Everyday mobile (Phone Plan 20: unlimited national calls, 3gb month data).
Despite originally getting my S10+ phone from them, they are forcing me to upgrade to a $28/month plan with 5G access (despite not having a 5G compatible phone).
Seems crazy, as I don't think the current plan was anything special. Favored them, yet they are forcing me to go elsewhere as there new $28 plan (which I cannot even find on their site, is even less special).
Go figure, because I cannot.
To be honest, I didn't even think that they could force me to change from a grandfathered plan.
Have you read the terms and conditions, specifically
