GPS signals pass through the ionosphere which greatly affected by solar 
weather.

Terrestrial cellphone signals do not pass through the ionosphere, so 
flares don't necessarily change things.  There is anecdotal evidence, 
though, that solar activity can change the environmental RF background 
noise level, and that could have an effect on cellphone link margins.
