What happens when a mobile proxy line drops
Mobile connections reconnect and change IP by design, so a brief drop is normal. The useful skill is telling a routine reconnect from a real fault, and knowing the two checks that separate them.
A mobile line is not a fixed cable. Handovers, reconnects, and IP changes are normal, and a short drop during one is expected. The question is never whether it can drop, but whether this drop is routine or a fault.
Rotation versus a drop
A rotation is deliberate: you asked for a new IP and the modem reconnects. A drop is the same reconnect happening on its own, often after a carrier handover. Both change the address and both are brief.
What a normal reconnect looks like
The connection is refused for a short window, tens of seconds, then comes back on a new IP. Your host, port, and credentials are unchanged. A retry a minute later usually succeeds.
A monitored line replaces a genuinely dead modem, so a drop that clears itself is not worth escalating. Save the report for a line that stays down after the window has passed.
Telling a hiccup from a dead line
Two checks separate a routine reconnect from a real fault. Run them before you escalate.
- Retry once after the window has passed.
- Run an IP check to see whether the address came back.
- Try the same settings on a phone hotspot.
- If both fail the same way, it is not the destination network.
- Contact support with the error text and the endpoint you used.
What to do on a drop
Do not hammer reconnects the moment it fails. Wait, retry once, and check the IP. If it stays down and a hotspot fails too, that is when support helps, with the details from what to check when a proxy will not connect.
What to expect for up time
A dedicated modem is monitored, and a genuinely dead line is replaced. The published expectations sit in the reliability SLA. Treat a brief reconnect as normal and a sustained down line as a fault to report.
Is a brief drop normal?
Yes. Mobile lines reconnect by design, especially after a carrier handover or a rotation. A short drop followed by a new IP is expected behaviour.
Does the IP change after a drop?
Usually. A reconnect makes the carrier assign a fresh address, and your host, port, and credentials stay the same.
How do I know it is not my network?
Try the same settings on a phone hotspot. If it works there, the line is up and the other network is filtering the port.
What should I send support?
The exact error text, the endpoint you used, and whether a hotspot failed too. Never send the password; support does not need it.
