Actually there's better way to fix it. The tire has to be dismantled from the rim and then some piece/layer of rubber patch will be pressed using a special machine so that the rubber patch will get blended into the tire rubber. I've tried this kind of repair before in Jakarta, even though it's not on the side wall but the mechanic said this technique is good enough to also fix sidewall puncture like that. Judging from the way it's done, seems pretty safe. Last time a shop in PJ offered me this exact method when I wanted to fix one puncture.
Yes, there is a few other ways. Internal patch method. Internal patch method with plug, Internal heat method, but still not advisable for sidewall, as the sidewall is always flexing and anything stuck to it can still come off in the long run.

Well yea, I guess it still depends on how bad is the puncture. If it's torn quite big and even worse that the steel belts are broken, then of course have to replace. But if it's only a small rubber hole, then there's still a chance, especially if you just drive normally (not high speeding or hard cornering).
Sidewall do not have steel belts. They usually have nylon or polyester, depending on their make and some are 1 ply and some are 2 plies. Steel belts are always at the thread pattern area only. Steel belts helps to keep the thread pattern in contact with the ground, whether when going straight or in corners. If really need to use, put it in the rears.....

it can be done from the inside, but most shops dont have dat special patch. ive only seen one shop have it, 15hengget per patch, it was satisfactory when they did it for me. i would rather have dis patch for every puncture on any of my tyres, but most shops dont even know dis type of patch exists
Internal patch with plug like this one...
Instruction also shows repairs for thread pattern area only....
Got the pictures from Weng Tat in Subang. They have them. Use these when kena a slightly larger hole where the normal plug in don't work...
