I have purchased the Magenta XL prepaid sim card with 14gb about one week ago, yesterday I received a message that my data was completely consumed and I needed to top up my balance I went on telekom website to purchase 15 eur balance but it did not work, I went to telekom shop where I bought 20 eur balance but still no internet in my phone, I dial *100# and it says my balance is now 35 eur but I dont have access to internet despite I have a good network (3 bars) and it shows 5G on my phone but no internet connection is made, what seems to be the problem?
