Im surprised that no ewallet yet including TnG that allowed wallet topup using mobile phone credit. That could be useful in some situation.

I believe it will make people spend more on telco credits if the usage is more broad. In account credits doesnt matter because the transaction already took place. They already have our money.

Im not saying telco credit become ewallet, im saying reload ewallet using money in telco credit. specifically TnG since TnG can reload using pin and most telco app can already buy voucher code/generated coupon for a lot of store. Its essentially just turn our mobile credit to coupon/voucher code. But I understand its probably prone to abuse like some members here said and I accept that answer.

Shopee cashback through TNG need to pay using TNG wallet?.

I dont understand. TnG cashback is in rewarded in points or cash?
