Where can i find the original charger for watch 4 in India

How is the LTE performance in galaxy watch 4. According to my scrutiny of messages people have mostly purchsed the Classic varient and they are the one having the issue. Can anyone with Galaxy Watch 4 can share his experience with LTE.

Does the LTE overheating issues is persistent to every user?

Do the charging issue in the S20 FE is solved after the second April update. If any other change please let me know!!
