I’m planning to take up umobile i90 plan because of their free roaming Roam - onz in Asia countries . May I know anybody used the roaming is it ok ??

I want to get the plan together with iPhone X , most of the stores no stock 256gb silver
Why umobile so lousy cheapskate ? All other telco got stock , all apple stores got stock , there’s actually no shortage of supply , yet umobile is the only champion no stock
