Twilio SMS alerts from your own number.

When a check fails, Uptimia sends the text through your own Twilio account: your sender number, your Twilio rates, and not a single message off the SMS allowance in your plan. Any handset with a signal receives it — no app, no data connection.

A push negotiates. A text arrives.

An app push needs a live data connection, an operating system willing to show it now, and a Focus mode that lets it past. A text from a number saved in your contacts follows the rules your phone keeps for people.

Technically it arrived. Practically it sat in a grey stack behind a sleeping screen, handled by the OS exactly like a social app’s nudge — because to the OS, that’s what a push is.

The sender is a fixed number you own, so it lives in your contacts — its own tone and a pass through Do Not Disturb. Phones rank people above apps; this puts your monitoring on the people side.

The fix isn’t sleeping with Do Not Disturb off. It’s an alert from a fixed number your phone is told to trust. Here’s a Saturday-night outage, end to end:

The night nginx stopped answering

03:12 on a Saturday: an unattended upgrade rewrote a vhost, the freight portal started refusing connections, the phone was on Do Not Disturb — and the biggest customer sits five hours east, already at work.

Connect Twilio in three steps

This channel is for people who keep their own Twilio account: Uptimia decides when to text, Twilio carries the message, and the number, the rates and the delivery logs stay yours. Wiring it up is four values, copied.

Step 12 min

Paste the SID, token and numbers

In Alerting → Integrations, choose Twilio, name it, and fill four fields: Account SID, auth token, the Twilio number that sends and the phone number that receives. Then hit send test.

Step 21 min

Teach your phone the sender

The sending number never changes, so save it as “Uptimia Alerts”: pin the thread, give it a tone you’d wake to, allow it through Do Not Disturb for the 03:00 kind of alert. Then point monitors at it.

Which checks text your number

Twelve monitor families write their own SMS: uptime, transactions, page speed, real-user monitoring, SSL, domains, malware, servers, heartbeats, blacklists, DNS and API checks. Eight are drawn here; every one of them texts the number you chose.

Choose whose handset buzzes

An SMS lands on exactly one handset, so routing is refreshingly concrete: your number, a teammate’s, or the on-call phone that changes hands on Mondays. Each is its own contact in Uptimia.

The evidence behind the text

The text carries the headline; everything else waits behind it — per-region results, incident timelines, public status pages and monthly reports from 171+ checkpoints in 70+ countries.

The dashboard where the acknowledgement lives

The text is one line, so the dashboard is your next tap: the full per-region verdict, the response-time chart, and the acknowledge button that halts the escalation ladder.

On an escalation policy — Professional plan and above — ignored alerts climb: the next number after your chosen delay, then the next channel. Planned maintenance sends nothing at all.

How Twilio SMS alerts work

Uptimia watches your websites from 171+ external locations in 70+ countries and, when one fails, sends a plain-text SMS through your own Twilio account — from your Twilio number to any phone you choose. Connecting takes four values from the Twilio console: Account SID, auth token, the sending number and the receiving number. Because the sender belongs to you, the alert thread is a contact you can pin, ring-tone and allow through Do Not Disturb — and it never changes. Uptimia adds no per-message fee and spends none of the SMS allowance in your plan; Twilio bills your account at its standard rate. When the site recovers, the all-clear arrives in the same thread — for uptime, transaction, speed, real-user, server, heartbeat, blacklist, DNS and API checks it carries the total downtime.

“The bundled SMS pack has me covered”

When the message allowance runs out

Alert #7 tonight

Nothing arrives
or it comes from a stranger’s shortcode

Metered bundles and shared shortcodes fail at the worst time: the meter empties on a long night, and a rotating sender can’t be saved or let through Do Not Disturb. Owning the pipe removes both.

What actually lands in the thread

Six shapes of message cover an incident’s life — all plain text, all readable on a lock screen or a ten-year-old handset.

Twilio SMS alerts FAQ

01Do I need my own Twilio account?+
Yes — that’s the point of this channel. Uptimia sends each alert through your Twilio account, from a number you own, at Twilio’s ordinary rates, with every delivery visible in your own console logs. If you’d rather not run one, Uptimia also has a built-in SMS channel with no setup at all; this integration exists for people who want the pipe in their own hands.
02What exactly do I have to configure?+
Four values, all copied from the Twilio console: the Account SID, the auth token, the Twilio number that should send, and the phone number that should receive. Save, send the test message, and the channel is live — no code, no webhook, nothing to host.
03What does each alert cost?+
Uptimia adds nothing — Twilio SMS is a standard alert channel on every plan, and it spends none of the monthly SMS allowance that comes with your plan (those credits belong to Uptimia’s own SMS channel). Twilio bills your account its usual per-message rate for the route, so an incident that opens and closes costs two ordinary SMS, itemised in your own Twilio console.
04Can Uptimia phone me instead of texting?+
Not through this integration — alerts are text messages; no calls are placed. If the goal is being woken reliably, the same properties do the job: save the sender as a contact, give it a loud tone, allow it through Do Not Disturb, and put a second number on the escalation ladder (Professional plan and above) as insurance.
05Can several people get the texts?+
Yes — each recipient number is its own contact in Uptimia, so add one Twilio contact per person (the SID, token and sending number can repeat) and attach monitors to any mix of them. Teams running a single rotation often point one contact at a shared on-call handset instead, and simply pass the phone on Mondays.
06Will carriers filter the alerts as spam?+
The texts come from your own Twilio number with low, bursty volume — the opposite of a spam profile — and on your own phone a saved contact is never filtered. One note for US recipients: Twilio requires A2P 10DLC registration for long-code senders; its console walks you through that once.
07Does it work when I’m abroad?+
Your number travels with you: SMS follows the SIM through roaming, so alerts reach the same thread wherever the phone finds signal — with or without a data connection. And the recipient number itself can be in any country Twilio can deliver SMS to.
08What happens if I sleep through the text?+
The escalation ladder (Professional plan and above) is the safety net: after the delay you chose, the alert moves to the next number or channel, and keeps climbing until someone acknowledges. When the monitor runs on an escalation policy, the down text carries a signed acknowledge link — one tap in the phone’s browser, no login, and the ladder pauses. Without a policy, you acknowledge in the dashboard.
09Which monitor types can send texts?+
Every one of the twelve — uptime, transactions, page speed, SSL, domains, malware, real-user monitoring, servers, heartbeats, blacklists, DNS and API checks all format their own SMS alerts. Nine of them put the total downtime in the recovery text; SSL, domain and malware recoveries give the time they went healthy instead.
10Is this channel available on all plans?+
Yes — Twilio SMS is one of 12 built-in alert channels, included on every plan and in the 30-day free trial, no credit card needed. The only per-message cost is the one Twilio itself bills to your account.
