you're about thirty seconds from online.
this is the card in your box, but longer. same three steps, same light, same email at the end.
insert a SIM.
the tray is on the side. the pin is in the quickstart card — pop it out. any nano-SIM with a data plan on a supported network works. in the US: AT&T or T-Mobile.
plug it in.
any USB-C port on your Mac. no driver, no app, no account, no captcha.
there is no step 3.
the light pulses while it finds a network, then goes solid — about three seconds. your Mac sees relay as ethernet. everything just uses it.
one light. five states.
the light is white. it tells you everything the missing app would.
| state | meaning |
|---|---|
| off | no power. try another port — some hubs under-deliver. plug in direct. |
| slow pulse | searching for a network. normal for the first ~10 seconds. |
| solid | connected. you're online. |
| double blink | no SIM found. eject the tray and re-seat the SIM. |
| fast blink | SIM in, no service. check the plan is active and includes data. |
work down this list.
relay needs 5G SA or LTE. in the US that's AT&T or T-Mobile — Verizon isn't supported yet.
check the SIM.
it needs an active data plan on AT&T or T-Mobile (or an MVNO on their networks). a Verizon SIM — including Visible — won't connect at launch.
plug in direct.
skip the hub. some hubs under-deliver power, and the light will tell you — if it's off, it's the port, not the network.
use the extender.
weak bars? the 15 cm braided extender in your box isn't decoration — distance from the aluminum chassis genuinely helps the antennas breathe.
re-seat the SIM.
double blink means the SIM wasn't found. eject the tray with the pin, re-seat the SIM, push the tray home until it's flush.
give it ten seconds.
a slow pulse is normal while it searches — especially the first time on a new network. solid means done.
still stuck?
email kavin@relay5g.com — a human replies, usually me. tell us what the light is doing; that's usually enough.
