SMS alerts for website monitoring, no gateway.

Uptimia watches your sites from 171+ locations and texts the number you already answer. Setting it up is one field: SMS is a built-in contact type, so there is no messaging account to open and no invoice to reconcile.

A phone number, not an account

Text alerting usually means a gateway to sign up for, a sender ID to register and a per-message invoice to reconcile. Uptimia sends the message on its own account instead.

The usual way to add texts

A vendor, a sender ID, a bill

A check fails
you would like to know by text
sign up · register
A messaging vendor
API keys, sender IDs, monthly billing

Uptimia supports that route too, through the Twilio integration. But it is a procurement task before it is an alert, and afterwards the carrier invoices you directly for every message.

The number sits in your contact list beside the email addresses. Uptimia sends the message on its own account and takes one credit from the monthly SMS allowance your plan already includes.

You are not buying a messaging product. You are typing a number into a contact. Here is a Sunday evening, end to end:

The night nine monitors fell

21:14 on a Sunday: a database stopped accepting new connections and nine checks failed inside ninety seconds. The dashboard filled with nine red rows. The phone showed one text, because those nine monitors shared an escalation policy.

Nine failures. Two messages. One phone that stayed sane21:31
Alert every monitor separately and the same broken database is eighteen texts — nine down, nine back up — and by the fourth nobody is reading them. The ladder is what keeps the ninth one worth opening.

One field: the number you answer

SMS is a contact type, not an integration — nothing to connect, nothing to host. Add the number in international format, point monitors at it, and decide when it may ring.

Step 130 seconds

Add a contact of type SMS

On the Contacts page, pick SMS from the channel grid and type the number in international format, starting with a +. Save it and the contact can take alerts; Verify texts a code to prove the handset is yours.

SMS · +370 6·· ··· ··9 Verify
a code texted to that handset · one credit spent
Step 21 minute

Point monitors at the number

Attach the contact to one monitor or to all of them. Every monitor keeps its own recipient list, so the checkout can text you while the staging box only sends email.

Decide when it may ring

Quiet hours are set per person, so nights land on whoever is on call. Planned maintenance texts nobody. Put the monitors on an escalation ladder and an unacknowledged alert moves to the next number on its own — ladders come with the Professional plan and above; SMS alerts themselves work on every plan.

Twelve monitor types, one number

Pinging the homepage tells you about the homepage. A certificate weeks from expiry, a checkout failing on step four, a backup that never checked in — each writes its own one-line message, and each sends its own recovery.

SSL certificatesExpiry, with weeks of warning

Confirmation, folding and scheduled silence

A text costs a credit and a night's sleep, so every other channel can afford to be chatty and this one cannot. Three rules decide whether a message is worth sending, and all three are yours to set.

Confirmed, then sent
One unlucky probe never gets to wake you.
Up to three regions must agree before an uptime alert sends
Retried up to five times if sending fails
A recovery text follows when the check goes green
no single-probe false alarms

Monitors on one escalation ladder — Professional plan and above — alert together.
Monitors sharing a policy fold into one text
Monitors that join later update it

What the 160 characters leave out

A text is the interrupt, not the report. The confirming locations, the response-time chart and the incident timeline sit in the dashboard behind it — and they are still there on Monday morning.

Where the evidence lives

The text names the monitor, its status and the minute the incident started. The dashboard keeps the rest: which locations confirmed the failure, what the response looked like, and an acknowledge button if you skipped the link.

It says Uptimia, not a number

Texts arrive from the sender name Uptimia. In North America and around sixty other country codes, where alphabetic senders are not permitted, they come from one fixed long code instead.

Included, not invoiced

Texts come out of a monthly allowance that resets on the 1st. No per-message fee, and nothing to top up mid-month.

Running low is never silent

Uptimia emails you once a month when the balance drops to 20% remaining, and again when it hits zero. Texts pause; every other channel keeps going.

On an escalation policy — Professional plan and above — an ignored alert climbs: the next number after the delay you set, then another channel entirely. Planned maintenance sends nothing at all.

How website monitoring SMS alerts work

Uptimia checks your websites from 171+ external locations and, once up to three of them agree an uptime check has failed, sends a plain text message to a phone number on your contact list. Setting it up is a single field — the number in international format — because SMS is a built-in contact type rather than a connected integration: there is no messaging account to open, no sender ID to register and no per-message invoice. Each text names the monitor, its status and the minute the incident started, inside one 160-character message. Messages are drawn from the monthly SMS allowance that comes with your plan. Put monitors on a shared escalation policy — Professional plan and above — and a storm of failures folds into a single text with a signed acknowledge link, and the recovery message reports how long the incident lasted.

“Email at night is good enough”

Mail waits. A text arrives

Checkout down 02:40
the email is sent immediately
unread until 07:00
The inbox
batched and silent overnight

The mail was delivered on time and read four hours late, because a phone treats mail as reading material. Email is the right channel for the evidence — it is the wrong one for the interruption.

no app, nothing to install

The check runs outside your infrastructure, so it sees what a customer sees; the text arrives on the one channel a phone still shows unasked. Neither end needs anything installed.

SMS alerts FAQ

01How is this different from the Twilio integration?+
This is the built-in channel: you type a phone number, Uptimia sends the message on its own account, and it counts against the SMS allowance in your plan. The Twilio integration is for teams who would rather own the pipe — your account, your sending number, your bill, and no allowance to run out of. Same alerts either way; the difference is who the carrier invoices.
02Do I need an account with a messaging provider?+
No. That is the whole point of this channel — there is nothing to sign up for, no API key to paste and no sender ID to register. SMS is a contact type in Uptimia, exactly like an email address: add the number, attach it to monitors, done.
03How many texts do I get, and what do they cost?+
Each plan carries a monthly SMS allowance that resets on the first of the month — 20 during the 30-day trial, then 50 on Basic, 150 on Professional and 500 on Enterprise. One message spends one credit, and the code that verifies a new number spends one too. Uptimia adds no per-message fee, and there is no top-up to buy: if you need volume beyond the allowance, the Twilio integration bills the carrier directly instead.
04What happens if the allowance runs out?+
Text alerts pause; every other channel you have configured keeps going, so you are not left unmonitored. Uptimia emails you once a month when the balance drops to 20% remaining, and again when it reaches zero, and the skipped messages are recorded in your SMS log — it is never a silent stop.
05Which countries can Uptimia text?+
North America and most of Europe, plus Japan, South Korea, Australia, New Zealand, Singapore, India, Brazil, Chile, Argentina, the Philippines, Türkiye, Taiwan, Hong Kong, the UAE, Oman, Bahrain and Uruguay. Numbers outside that list are declined when you add them rather than failing silently later. If your number is not covered, the Twilio integration or WhatsApp will usually reach it.
06Who does the message come from?+
The sender name Uptimia, so it is recognisable before you open it. A number of countries do not permit alphabetic sender names; there the text arrives from a fixed long code instead, which you can save as a contact once and recognise from then on.
07Can I tap something in the text?+
Monitors on an escalation policy (Professional plan and above) get a signed acknowledge link in every down text — it works without logging in, and one tap pauses the ladder. The link is dropped whole, never truncated, when the message would otherwise pass 160 characters. Monitors alerting all recipients at once send plain text with no link. Messages are in English on every account.
08What if the message fails to send?+
Uptimia retries with a growing delay, up to five attempts, before giving up on that notification. What it cannot promise is a delivery receipt: carriers do not reliably report one, so treat the escalation ladder — a second number, then another channel — as the real safety net rather than any single text.
09Can several people get the texts?+
Yes. Each number is its own contact, so add one per person and attach whichever monitors matter to them. Quiet hours belong to the person who owns the contact — set account-wide, not per monitor — which is how a rotation works in practice: your number sleeps, the on-call number does not.
10Which monitor types can text me?+
All twelve — uptime, transactions, page speed, real-user monitoring, SSL, domains, malware, servers, heartbeats, blacklists, DNS and API checks. Each writes its own one-line message, and each sends its own recovery text when the check goes green.

One number. Then downtime texts you.

Add the number, verify it, attach it to the monitors that matter. From then on the worst news of the week arrives the way the rest of your life does — as a text.
