Just checked and mine is still set to 30 amps. I verified the CDMA modem is still in there, but since Blink cancelled the service the log shows there is no modem.
If you want to manually change your current, here are the instructions:
On the Blink, click on Settings, then Device Info. Press on the 30A under Maximum Current and hold your finger there for at least 10 seconds. This will take you to a screen asking for the code, the current code is 906598. Then you'll be in Maintenance Mode and be able to change the Maximum Current.
