Ratings and reviews

Bad customer service, don't waste your time with them or there mother company. Bought start packet with sim card then identified myself and didn't want to activate the sim card. reason is company policy that is unknown for the customer and won't tell me why. Avoid jamobil and Congstar(mother company) as possible.

New update logs you out of your account. Then no matter what you do it says your credentials are incorrect, even when they are. This update is absolute dog doo doo. Edit: responding to the reply from the developer. There is no way to provide feedback from within the app because there's no button except logging in, which doesn't work, hence I am here. You already know what version of the app it is, the current one and I'm on the android store, do your job.

This prepaid line will force you to hear a bot message every single time you make a call that "reminds you" to put money into your account. They conviniently sell the 10€ credits for plan that are worth 8€, and since the account balance is now under 2€ you will be forever forced to listen to these messages. Doesn't matter if the plan has limitless calls and sms like mine. Better off buying another prepaid company 100%.
