Get the job done and follow what your moral compass says right.. I guess she might 've agreed the salary and perks ( watvr may it be) bfore coming to u . So wat all u do or give to her more than wat u've agreed is extra , technically. Still, as u say, if she is worth more, give her more!!.
Abut giving the Qtel card or phone, here, this solely depends on the trust u've put on her and that takes time obviously( its the day one only, need some time to know more). May be later u cud think about giving her a mobile allowance, but be careful..coz wen u hire a maid, u 're more like a guardian too.. Think abut it..

---If you can't CONVINCE them, CONFUSE them!!!
