  • How long is my yallo calling time credit valid for?

    yallo calling time credit is principally not subject to time limitations. However there are rules regarding the validity of the mobile phone number: if no calls (incoming or outgoing) are made with yallo during 12 months, the yallo phone number will be temporarily deactivated. The number can be reactivated with yallo during the following 6 months. If nothing is done during these 6 months – i.e. after a total of 18 months of inactivity – the phone number will be definitively deleted and the existing calling time credit on the respective SIM card will expire.

  • When will an automatic refill be carried out?

    Your remaining calling time credit is checked once a day. That is why it is possible that a refill is not carried out immediately despite dropping below the set limit for your calling time credit. It is recommended that you set the limit for your calling time credit such that the remaining balance will last for at least 1-2 days (for your regular mobile phone use).

  • Can I combine several automatic refill options?

    Yes, you can combine the refill options "Automatic Refill", "Monthly Refill" and "Refill On the Go" as you like and activate them at the same time.

    The maximum amount per day is CHF 200.-, per month CHF 500.- (depending on the type of refill). If you have reached this limit, additional refills can be made via your yallo account or our yallo partners.

  • Why was my automatic refill not carried out despite having a low credit balance?

    Please note that your calling time credit is only checked once a day. That is why it is possible that a refill is not carried out immediately despite dropping below the limit set for your calling time credit. We recommend that you set your limit such that the remaining amount will last for an additional 24 hours of your regular use.

  • Why was my monthly refill not carried out?

    There are various reasons why an automatic refill might not be carried out. The mobile phone number can have the wrong status ("locked" / "blocked"). Or you have reached your daily (CHF 200.-) or monthly (CHF 500.-) limit for refills. There might be a problem with your credit card.
