if my maxis plan is not supported 5g in Malaysia, can i get 5g while roaming under singtel for example?

As a Maxis user, how do we activate 5G roaming?
You will be able to enjoy 5G while roaming in selected countries if you meet all the following requirements:

An active 5G access pass on your plan or subscribed to Maxis Business Postpaid plans with 5G;
Purchased a data roaming pass in a 5G enabled roaming country, check here;
5G capable device. For a list of 5G capable devices please check here;
4G LTE SIM. To check, just dial *100*8*5# from your phone; and
Enabled 5G settings on your device.

if i purchase rm10 for 10gb 4g/5g data pass mean i can get 5g roaming?
