Positives:
+ Order through Amazon as usual without any problems
+ Fast delivery of the SIM card
+ Detailed description of activation
+ The monthly cost of 3.95 EUR will not be beaten, otherwise I had only by a few calls from a landline phone to have around 5 EUR / month together
+ 500 MB are quite rare, and certainly not at the price
Negatives:
- SMS, free minutes and amount of data are counted from Discotel differently from my phone (Sony Xperia J): According to Cell I've written 73 SMS, according Discotel bill 102 SMS! Similarly, in the free minutes and the data, where on the bill are given considerably more than in my cell counter.
- The Service Center is very confusing
- The first registration with password assignment is annoying because the page constantly complains and does not accept my password.
- In the O2 network is to get on the land only poor or no reception. Only close to the city makes phone calls and surf fun
Still, I highly recommend the All-In-100-deal for 3.95 EUR. I save a few euros a month by which I would otherwise have to pay for it on the landline bill. And in addition I can adequately write many SMS and surf relatively long fast. Top.
