Yes, i faced the same problem too on activiting the roaming.
My case
1. Mnp on sunday and got the sim card
2. On monday i went oversea , my previous line was deactivated by afternoon, changed to umobile sim card but still no line
3. Call and check with umobile, basically u need to pay 300 deposit and personally went down to umobile center to request for it, with ur ic and passport copy
4. I very sure i checked the p50 udata 10/day t&c, it nvr mention about tis requirement, but it does mentioned in databackpack website.
5. No choice as i am aldy oversea,i cant really do tat , they offer me alternative solution, to enroll autodebit
6. I concern on the autodebit process tat will take days (the form mention about 14 days), so on tues, i ask my bro to pay the 300 deposit on my behalf , with my ic and passport, but they still reject.
7. No choice had to called umobile customer service, and had a long quarrel with them, they still insists not accepting my 300 deposit pay by my brother (cant really understand , i am paying u money, not taking money from you, u still dont want to accept)
8. No choice, at oversea, i filled in the autodebit form and send them my personal documents like ic, passport, and credit card, etc, (luckily i always keep softcopy in my cloud service) , after email tell them to expedite on the process.
9. Wed ard afternoon, received email to fill up another form to activate the roaming service.
10. Few mins later roaming activated
Overall not a very good experiece, was out of contact for 2 days , from monday afternoon to wed afternoon, dun knw i had missed out how many calls from my client, just hope my boss wun fire me for tat
btw plan to lodge in a formal complaint about his matter when i am free , from my point of view this whole procedure is no logic at all, u prefer ppl to enroll ur auto-debit by reject ppl paying u 300
i really cant brain their iso standard or those who review their procedure

pls fire them
for number 7, yes u need to ownself go only can. This is for safety reason, unless u have a letter authorize your bro to pay RM 300 for you.
Dun worry, just tell yr boss what happened will do, if he fire you while u have a valid reason, report to Labour Department.
