So far no prob. Cos of msia shortage that's why Ezlink partnered with tng.
I believe what you mean is that you can't top up RM in Singapore. That's why need to buy and top up in msia. And what some peeps practise is: when it's their turn, borrow from car behind cos they can't use their ezlink tng card yet. Most decent sinkies would assist
Or long bang some friends going into msia to top up like now if you are up mountain. Long bang yourself. Hahaha.
If you have the msia vep rfid, then no issue at all. Sometimes I let the rfid deduct instead of using my eztng card.
Tried and tested no fewer than 10 times liao.
