Have you guys tried mPay? It only works with MTC but its really a time saver. Nat has a prepaid eeZee line and I used to recharge it for her using the MTC website which although easier then passing by the bakala and getting a refill card, it was still not easy enough for my lazy ass. mPay on the other hand makes life really easy. You sign up with them for free and you then get a menu on your phone allowing you refill other peoples phones (or yours) with just a few clicks on the phone. The amount then gets deducted from your bank account.
So for example I just went into my mPay menu on the phone, and then clicked on reload and then clicked on KD5 and then chose Nat and I then clicked on confirm. Right away I got an SMS telling me that I had transferred money onto Nats prepaid card and she also instantly got her phone recharged. Its that easy.
You can check out their website by going to mpay.com.kw but to sign up just pass by any Fono branch (like the one at Marina Mall) and they would set it up for you right away. I like stuff that makes me lazier.
