Seriously, I think people would have a better deal with #firsty free if they really can't afford anything yet still need data and can be fine with 300 MB/day, but that's a #DataOnly - #eSIM with a shitty #app (tho they use #ads instead of #Tracking as #payment model), but I'd rather recommend some different options even if one can only afford very little.
Again: If you want something to be actually reachable, a regular-ass #prepaid #SIM (or eSIM ffs...!) will be a better choice anyway.
And if you only want #data and only need very little of it, there are even cheaper options.
