Means can only receive OTP sms anytime overseas (free), no problem. Cannot receive roaming call while overseas, cannot call out via mobile while overseas and cannot send out sms while overseas.

just ported in to Zym 5G+. Odd that I'm only getting 100+mbps DL, but 600-800mbps DL in CL. Is it because M1 less users?

When i test M1 Maxx 5G, their dl and ul speed is definitely way faster during speed test than Singtel but M1 coverage much lousier.

It will depend on the location.

No issues to get greater than 500 Mbps speed with non-SIMBA 5G plans.

But yes, my record speed comes from M1 Maxx.

1) My historical best result from Singtel network.
Singtel SIM Only plan at S$20.37 per month, Poco X4 GT result back in Oct 2023, beside Jurong Point Singtel Shop.

2) My recent best result from Singtel network

My Singtel S$15.28 per month plan 5G+ using a Poco X7 Pro, recent test results, Open Area between two HDB buildings, Jurong West, near to Jurong Point.

3) My overall best result is from M1 Maxx and I only used it for one month.

has anyone tested their roaming?

 

[ryouma]

i tested on about 4-5 locations around Singapore and the speed are pretty much consistent
Singtel (Zero1 and Zym) and m1 (CL). Rather disappointing tbh

 

[orhkia]

Unlikely to be true. Change to psim is only 1 time charge not monthly charge

In general, if you need to have physical SIM Card, do not sign up using SingTel hi! Website link which will only give you eSIM. Go to the authorized dealers.

And if the Authorized dealers say the physical SIM card costs two dollars extra per month, then report to SingTel. That should not be the case.

On the other hand, one time charge to convert eSIM to physical SIM is possible but I do not know the charges. Better to avoid such situation in the first place.

Ya that i was thinking should be one time payment for physical sim also.

Darn I was just about to port a line from Gomo over... So what's is the cheapest route now for Singtel network users to take advantage of Hi's offer?

Indeed.

This is probably because of the limited time offer for the S$13 5G plan port-in offer (new sign-up price is at S$15 per month).

No change to the S$10 4G port-in offer (new sign-up price is at S$12 per month).
