A similar thread...
I have a 3G Prepaid Simcard for many years now, I want to keep the number but I want it to be 4G.. How to make it 4G speed?
And the same answer to your question :
From what I know, Globe is just offering limited PREPAID LTE marketed as a Tattoo LTE Prepaid Sim. It has a special number series which is entirely different from the regular Prepaid sims.
To answer the question, that service is not yet available but could be in the future.
