I think the major complaint with 4G is no network inside underground trains network...

My 10.10 plan still got 5G. Guess once no more, time to port out to Maxx or Eight for 1-2 months? Before porting to Z1 for the free 6 months (provided they still continue with the promotion).

Vivifi is until further notice, and they have not served the notice to end the promo.

Zero1 still says 31 Oct, but that might change soon.

IDD is free on MVNO. If not, your phone issue best checked with zym support

After some check, I realised the problem was from ZYM, refer to screenshot below.

Anyway, I contacted ZYM customer service via WA, they refresh for me and now it's working, most likely since day 1 it was already not provision properly (I recently ported), didn't realise as I was overseas and only just came back.

Small issue can solve ok la.. since I'm paying only $7.5 I'm ok.

Unlikely some telco, pay $75 10 times of what I'm paying at zym but really cmi.

Yesterday I was at suntec food court, my mobile data totally not working, when it finally work, the speed was only like 3mbps while zym was like almost 700mbps at the same place on the same phone.

After porting to maxx I must say zym is the best cheapest 5G NSA(soon to be SA) mvno...more stable and consistent..
