Ratings and reviews

After using this app. The loud speaker on Samsung note 8, 9 doesn't work for other apps. The sound comes thru the ear piece even when loud speaker is activated. But this is rectified when the jumblo app is closed. But after updating to android pie on galaxy note 9, this problem doesn't go away even after closing the jumblo app and the phone needs to be restarted. Pls rectify this.

I am using Jumblo for the last 10 years or so. Excellently usable app. It saved a ton of my money. Very stable service and the issues are supported and answered asap. The clarity is excellent. No such app has been so long standing and stable. Kudos to the team.

I am using jumblo since past 10 years. Excellent application. Only problem is while on net call, if there os a local call, then the voice becomes very low and the phone will hang.
