What you can verify about a Boston line
A Boston SIM is a Northeast identity apart from New York, which helps when your pool already has NYC IPs and you do not want all traffic to lead to one metro. The city is big in universities, biotech and finance, so the traffic looks like normal consumer use.
The carrier in the ISP field
An IP checker on a Boston line names AT&T, T-Mobile or Verizon as the ISP and cellular as the connection type. We publish the method; you repeat it on your own line.
The city in the location field
Boston or its state, depending on the carrier gateway and the database. The country is always the United States.
The SIM in the device
One physical SIM in one physical device in Boston, assigned to you alone for the term. No pool, no sharing, no relabeled address.
