I do a quick reply to you now.
(If I've time later -- I'll add phone screenshots to this post.)
I've tried a least two (2) different TPG top up providers on Shopee -- and the experience is the same:
1. Place order to top up your TPG account on Shopee (e.g. $10 top up)
2. During check out, provide your TPG mobile number -- just the 8 digit mobile number -- under the leave a message text box.
3. After payment, wait for the top up to your TPG account balance (this could range from a few minutes to multiple hours).
4. When the Shopee delivery status changed to -- item 'shipped out' -- top up to your TPG account balance is in process.
5. You'll receive an SMS on your TPG mobile -- once the top up has been done.
6(a) You can (then) check (both) your TPG plan usage/quota + account balance -- by sending out an SMS
on your TPG mobile -- type 'TPG' (without quotes) & send out the SMS to 1218.
6(b) After sending the above SMS -- you'll get a reply -- with a list of choices. Reply 2 to view balance.
6(c) The next SMS you receive --
shows an updated status of your usage/quota + current TPG account balance.
Whenever necessary, I use the above SMS method to check my TPG usage/quota + account balance --
so I no need --
to install/login to the TPG mobile app or login to the TPG Web site.
(You may wish to use above SMS method to check your current TPG quota + account balance --
BEFORE placing order on Shopee for the TPG top up.)
(If I've time later -- I'll add phone screenshots to this post.)
Hope the above helps.
