I decided to switch to HK Mobile's prepaid sim card (using CSL network) yesterday and port my number. Porting date is this coming Friday. First time switching from postpaid plan to prepaid so hopefully porting is successful. HK Mobile's FB page is in Chinese so not useful for me to get info there. Thankfully, they were able to respond in English using their whatsapp number. HK Mobile says I can refer to the info on CSL's website for HK Mobi prepaid sim because it is one and the same. They provided a location in Central (Mobile Phone Direct Selling Centre shop next to Worldwide House) that can do MNP so I went there instead of the Mypacemarket shop in TST.
@vyral_143 I asked HK Mobile about recharging and they said it was only through recharge vouchers whether getting the physical one or sending them a whatsapp where you pay them by fps and they send you the recharge code. Cannot recharge online using csl website.
Also, I asked them if there was a difference between sim card validity and data pass validity and they said that it follows whichever is later. For example the starter pack with MNP is $150, sim card validity is 365 days and includes data pass of 70GB / 2000mins / 365 days and free $38 bonus for MNP from other operator. He said before the end of 365 days, I can use that $38 bonus to subscribe to the data pass of $38 / 1GB / 365 days and this would automatically extend my sim card validity by another 365 days even if I don't recharge my sim card with a recharge voucher. He said this would give me 2 years use of the sim card even without any recharge. Also, he said that even if I recharge the sim early by putting in $100 now, this amount will be banked in the sim card and just be deducted by the price of any new subscription as long as I keep subscribing to a new data pass every year. Does this make sense?
I had the impression that sim card validity and data pass validity are 2 separate things. You would have to ensure sim card is valid (count from date of last recharge) to continue using the card (to receive incoming sms while in overseas, for example) and not lose your number. Subscribing to a data pass is separate and will only work if your sim card is still valid. From csl's website, I would need to use recharge vouchers worth $50/$100 to extend sim card validity by 365 days. Wouldn't I need to (A) ensure I recharge my sim before the end of the 1st year with a minimum of $50 in order to extend my sim card validity by another 365 days, and (B) optionally subscribe to a data pass if I want to..? Essentially, I need to continue doing A every year to ensure sim card remains valid but can choose not to do B if I don't need mobile data when overseas and just need to keep my number and be able to receive incoming sms?
HK Mobile is telling me, for example, with a one time recharge of $100, my sim card will not expire in 365 days (counting from recharge date) as long as I keep subscribing to $38 / 1GB / 365 days data pass every year as it will follow the later validity date of the data pass. This effectively gives me 2 years worth of sim card validity instead of just 1 year with that one time recharge of $100.
Appreciate any insight on how these things actually work as the last thing I want is to lose my number when I've already left HK. There isn't much handholding with prepaid sim service providers, which takes getting used to. And with prepaid sim cards, seems like the number is lost forever if you forget to ensure your sim card remains valid.
