Frequently Asked Questions
Mobile Plan
Mobile Prepaid
What is the difference between prepaid and postpaid?
The difference between prepaid and postpaid lies in the payment method. With prepaid, you have to load a credit balance in advance. You are billed from this. For postpaid, you pay the invoice in arrears. In the case of postpaid contracts, you also get an invoice at the end of the month and the amount is debited from your account. Postpaid contracts need a good credit rating. A credit check is therefore carried out immediately before concluding a contract.
Can I also use the internet elsewhere in the EU with my postpaid contract?
Yes, of course! Mobile internet is included in Switzerland, EU member states, Serbia, Bosnia-Herzegovina, North Macedonia and Montenegro with all our postpaid contracts.
Where can I take out a mobile phone contract?
In all MTEL shops, via our webshop at mtel.ch, at mobilezone, as well as by phone through our contact center on tel. +41784747470.
Are calls to Serbia, Bosnia and Herzegovina. North Macedonia and Montenegro unlimited in all postpaid contracts?
Yes, but only to the MTEL zone networks („mts“ in Serbia, „m:tel“ in Bosnia and Hercegovina, MTEL in North Macedonia and m:tel in Montenegro)
Does “Roam Like Home” mean that you can also use mobile internet elsewhere in the EU at no extra charge?
Yes, of course! Depending on the plan, you can also use the included data in the EU as well as in Serbia, Bosnia and Herzegovina, North Macedonia and Montenegro.
Where can I find current promotions?
You can always find the best promotions for mobile telephony at Deals.
How can I check my mobile data usage?
You can check your mobile data usage in your MTEL customer profile or via the MTEL app. There you can see your remaining data, minutes, and SMS in real time.
