How to Recover Lost SIM Card

I lost my phone to a thief last Dec 21, 2012. I was so devastated--not because of the cell phone unit but mainly because of the sim card. I learned from a friend that you can retrieve your cellular phone number from your carrier and so I went to a Smart  Store at Gateway Mall, Araneta Center (my lost sim card is a Smart prepaid sim). I brought the following requirements (see below) but I was told that my Smart Money card had expired a few months ago and further, that it was not linked to my lost cell phone number. I asked for any other remedy or solution but the customer service representative cannot provide one.

Unperturbed, I went to another Smart Store located at Ali Mall, Cubao, Quezon City. This time, I gained hope. While they likewise reiterated that my Smart Money was not linked to my number, they nevertheless asked for other proof of ownership. Take note that Smart's website says that "any" proof of ownership will do. I was told that an LBC receipt or similar kind may be accommodated.

I tried to find one at home but I think I threw them away. Anyway, to my surprise I stumbled upon my old sim card ownership certificate (half a paper's size) issued way back year 2000. Back then, such certificates are being issued for every puchase of sim cards. 

Of course, this was more than enough proof that I own the cell phone number. In short, they issued to me a new sim card bearing my old cell phone number.

Requirements:

For lost or stolen Smart SIM card, submit the following documents/requirements to any SMART Store.

1. Duly notarized Affidavit of Loss
2. Two (2) valid Proof of Identification
3. Any proof of ownership of the lost/stolen SIM card (PUK slip, SIM casing, personalized Smart Money card linked to the lost/stolen SIM card)
4. SIM replacement fee for P40 (SMART Prepaid) and P30 (Talk 'N Text).

Globe likewise issues new sim cards for lost or stolen sim cards with generally the same requirements.

Tips for easy recovery of your sim card:

1. keep your PUK slip or SIM casing.
2. link your Smart Money to your cell phone number.
3. keep other proof of ownership such as digitally printed receipts bearing your number
4. try other branches if a carrier's store doesn't seem to be accommodating.
5. try to produce first requirements 2 and 3 above before procuring an affidavit of loss because such document would be useless if you can not prove your ownership.
