No one is forcing you to change.
RW still allows those users that still use the “Legacy” model phones, those phones that are now several years old, long past End of Life on the old original “cheaper” Refund based plan. If you have such a device that is still working, wow, your lucky.
All carriers, industry standard practice, (not just in cellular companies), as time goes on, companies adjust their prices and add/remove available plans. Today’s economy, inflation, supply and demand, consumer market interest…all big factors. Also standard, that when one wants to change or upgrade their device or services, you can not keep your “grandfathered in” plan, as it is no longer eligible or even technically possible in RW’s case.
There are many other topic thread here discussing to death, and given very detailed explanations as to why RW has evolved and why the My Choice Plan now exists and its benefits. And is cheaper for data ($5 per 1GB vs $15 on the older plans)
The fact also stands, that there is no such thing as a cheap “Fully Unlimited” for talk, text, and LTE Data, cellular plan out there. All the companies even the small MVNO’s charge alot for such a plan. ($60+). IF you truly need unlimited data and are a heavy data user, then RW is not for you.
As a side note, i think the RW unlimited plan is so old that it runs on the 3G network to get its data. Now, it is a fact, that 3G network(Sprint) IS going away ever so slowly. So these phones will no longer be able to function in the soon to be future. Especially if/when the Tmobile merger is done and they start to transform the Sprint network over to TM.
