Hi altought I sent you a message yesterday I also would like to add some information here.
I bought the sim card on June 20th and started having trouble on July 20th. In the first month I had no problem and did renew my offer 5 times.
I still have 48.22GB to use on it.
Speestest results:
0.03Mbps Download / 0.00Mbps Upload
Vodafone Italy (Rome)
Ping 53ms / Jitter 538ms / 1.9% packet loss
0.03Mbps Download / 0.00Mbps Upload
Telecom Italia S.P.A (Pescara)
Ping 868ms / Jitter 897ms / 0% packet loss
Using Windows ping command through the Command Prompt (Phone hotspot) I've been able do ping Google sending 1 byte and got these results:
Sent = 73655, Received = 65230, Lost = 8425 (11% loss)
Minimum = 33ms, Maximum = 3513ms, Average 124ms
I've been in Pollutri for all this 32-day-period and as stated before in the first month had had no problem whatsoever. I've more than 50 Speestest.net results and the cmd ping results saved in a .txt file that I can send you if it helps on fixing this issue.
