I chose to upgrade to the $34, 50Gb at 5G speed.   My phone is Galaxy S10 plus. I know its not 5G phone but will the new plan work on the my phone at 4G speed.  I may buy a new 5G ready phone much later.

I helped my wife to the same new plan. her phone is Iphone 8 . again its not 5G ready. will the new plan work at least at 4G speed.

please I need Urgent expert advise.

I recently switched from a 3G plan to the 5G plan and was also worried if it would work on my phone. My phone also isn't 5G capable, though it's a different model than your phones, but the 5G plan works just fine still.

hi @sofa yes it will work. 5G plan is just about better speed. You can use it on 4G network with speed like 5G, 250Mbps
