I have a prepaid sim card and purchased two plans, 1 Onbeperkt Online, 2 5GB data traffic, speed 25MB/s.
Now of these two packages, only Onbeperkt Online is effective. Package 2 has not been able to take effect. As a result, I access the Internet at a very slow speed. Moreover, the package will expire in another month. I feel like I've been scammed. Your customer service phone number also does not provide English service, and the experience is really bad.
