I got Sunsim, and I notice that the number is one digit longer than usual - 0157020xxxxx vs my Vodafone 0173822xxxx

I'm wondering if this is why there is some difficulty reaching it from some providers, who may have a dialplan that does not allow for this

Do other e-plus and their mnvo SIMs have these longer numbers, or is this something gradually being introduced across all German networks?

This shouldn't matter too much for me if I only dial out via the Voipcheap callthrough access number, but I wonder what will happen if I attempt Voipcheap sms callback
