Easy Registration, Great Prices

Ja! Mobil is a great option for people who have just moved to Germany, or anyone who doesn't want the pressure of a permanent contract.

Their prepaid SIM card activation process can seem daunting, but this isn't their fault; they must abide by Germany's anti-terrorism laws which require registering SIM cards to an individual's identity, which in my opinion is reasonable as it helps cut down on identity theft & fraud- as someone from the USA who just moved to Germany, this is nice; the ease of purchasing "burner phones" in the USA is a recipe for all kinds of criminal activity.

Anyways, I appreciate their flexibility, straight forward registration process, and absolutely stellar prices. I went from paying $70/month in the USA to €14.99/month in Germany for the same services. Thank you so much Ja! Mobil, for making phones accessible to well-intended newcomers.

My SIM Card Is Still Not Activated Due to a Simple Document Mistake!

About 10 days ago, I purchased a mobile line from your company. During the activation process, I mistakenly uploaded my residence permit instead of my passport. As a result, the activation was canceled. I immediately contacted your customer service and explained the situation. I was informed that the issue would be corrected and I would be contacted. However, no action has been taken so far.

I also sent an email regarding the issue but have not received any response to that either.

I did not commit any offense—I simply made a human error by uploading the wrong document. It is unfair that I am unable to use a service I have already paid for. The fact that such a simple mistake has not been resolved for this long is extremely disappointing from a customer satisfaction perspective.

I kindly request that my line be activated as soon as possible, or that I be given a clear and prompt explanation.

I'm sorry to hear that. Sometimes replies via email can take a few days, especially when the issue needs to be addressed by a specialist team. Maybe try calling our Hotline and ask what the current status is.

I’m extremely disappointed with the way…

I’m extremely disappointed with the way Ja! Mobil handled my recent issue.

I received a text message warning me that my number would be canceled. Concerned, I called customer service, where the agent was kind and reassuring. She explicitly told me not to worry—that it was just an automated message and that, if my number got deactivated, I could simply call back, and they would reactivate it with a plan using my existing balance.

Fast forward a few days: my number was deactivated. I called back, only to be told that all my balance was gone—that this was common procedure and I would have to add new funds to reactivate my number.

I don’t have an issue with the procedure itself. What frustrates me is the blatant miscommunication and the refusal to take responsibility when service failure occurs. Had I been given accurate information, I would have topped up my account immediately and avoided losing my balance. Instead, I was assured that waiting would have no disadvantages—which turned out to be completely false.

This kind of misinformation is unfair and deceptive. A company should stand by what its representatives tell customers instead of making them pay the price for poor communication.

Thank you for your honest feedback. In principle, any credit given as a gift - for example from starting credit or credit notes - expires if the card is deactivated. You should have been informed of this.

However, purchased credit can be reloaded onto your SIM when the card is reactivated. If this has not happened, please contact our service team again. My colleagues will check this.

Awful service

Awful service. I can't believe how they still survive. I asked for refund after i stopped using jamobil. They haven't given the money back for months. I won't wait anymore and just report a file about this situation. I wonder what would they do if we didn't pay their money for months!!!! I contacted million times. They only put me off. There's no any logical excuse not to pay it back

I'm sure that if you contact our Customer Service again the matter can be resolved. Greetings Linda

Unprofessional, zero information, annulation of contract declined with false promises

I ordered the sim card online with jamobil. The activation process stalled because taking over my previous number did not work, fair enough. However I was not given the option to change my choice of using my old number, and I was left alone with having to assure that the number takeover works. Both online and via the app, there was zero information, the help page was an empty path. Completely unprofessional. I finally found a single email address as contact detail, and I asked for annulation of my contract which I supposedly had a right to for 14days. The declined with the argument that I bought the card in a shop which was wrong. Don't go for this company!!!

I'm sorry you had such a bad experience, I can assure you that it's not usual with us. Taking over phone numbers from one provider to the other is not always a smooth path and I can understand your frustration. However we do provide more customer service than just via email, there is also our Hotline and the WhatsApp Service, which are quite easy to find on our website. You just need to click on "Hilfe & Service" and then on "Kontakt". Greetings Linda

Could not make it work! Try another carrier - Activation process longer than getting a mortgage

Could not make it work. I get sim cards when I travel all the time. I just put it in and it works. Not with JaMobil. What an horrible service! How can they stay in business? After trying to activate online unsuccesfully, I tried the app with video call, providing all my sensitive personal info, passport number, passport picture, date of birth etc still won't work. How come they can't make it work easily like all other carriers?? Fraud risk are the same for other carriers .. no english service either. You have to translate all emails / instructions. They just pickup the money from foreigners & never provide the service.

Process set to only collect money

Is the process that every time that I switch tariffs in JaMobile, I need to lose money?
In all occasions where I switched my contract, I lost the days until the end of the period for the previous tariff.
Last week was frustrating – I ordered the change on Friday 17th of Sept 2021 and my old tariff was ending on 20th 23:59.
The new contract was supposed to start on 21st and you charged me full monthly fee for the time between 23:59 (20th ) and 01:05 AM (21st ) when you did the change.
1 full monthly fee for 65min caused by delay to start the new tariff on time and at the end your support personnel told me (case 0006112317 ) that it was my fault and I am not reading the instructions that I need to order the change on time.
My experience so far shows that a customer is never able to switch the tariff without loosing minimum 1 day and maximum the full 28 days (in the case above).
The process seems to be set always in JaMobile’s favor and I do not think I will continue to use your services going forward.
