If you have both the SIMs, keep both of them active on bare minimum credit and continue to enjoy the best benefits/offers which are still bound to come... no need to liter the garbage with the SIMs :-)

If you have one of them still, then stay with what you got and things should improve and will improve...matter of time only.

If you dont have any of the SIM/s yet then, why might you be in this forum ??? :-)

if you are the one, who is yet to have his/her 1st SIM ever in Qatar........ then OLD is GOLD :-)

Hope this helps..

Good Luck n God Bless
