Twilio Reviews 

I chose Twilio for WhatsApp OTP, and they forced me to upgrade, so I deposited $20. However, the exact same WhatsApp Business verification steps exist here as well — nothing is easier, and it’s even more expensive.

If you’re not a high-spending business, you can’t even reach support. Extremely low-quality service.

We’ve had a very disappointing experience with Twilio. Our account was hit by obvious SMS Toll Fraud, resulting in thousands of dollars of charges — including charges from a Twilio service (Authy) that we never enabled. Twilio’s own fraud protection tools (Fraud Guard, Geo Protection) failed to block any of the activity, and we had to stop the attack ourselves.

Support has been slow, inconsistent, and often contradictory. Despite providing logs and evidence, we were given shifting explanations (from “SMS Toll Fraud” to “Account Takeover”), none of which actually address the root issue or explain how Authy charges were generated on our account.

To make matters worse, our account was suddenly locked due to an unexplained –$1,600 balance that doesn’t appear anywhere in our billing history. Twilio has not been able to clarify where this number came from, yet requires it to be paid before they will even continue investigating.

After this experience, we’re actively looking to migrate to another provider. Twilio’s fraud prevention and support processes have proven unreliable and costly.

This company is a joke their system is specifically designed to make you pay, the trial is useless since you are limitated to do almost everything you can't even verify your own phone number through call.

do not even waste your time setting up the software . They have misc charges all over the place . a2p campaign took some time other than get set up once completed I had a question regarding the system so I can begin getting started I sent a ticket took 2 weeks to hear back and even then no answers . I cannot til this day get in contact with anyone over there so now I have to move forward with another software and start this whole process over again . A waste of my money a waste of my time and I'm truly pissed off that I spent so much time on this now I'm back at square one and for what .

I submitted all my documents and they still rejected my documents.

I don’t recommend twilio to anyone.

Just trying to sign up for SendGrid so that I could link it with my new CRM for sending emails to customers. As others have said, right after signing up my account was instantly closed and banned. I literally did nothing but gave them my email and phone number and chose a password, and for whatever reason it was "determined that Twilio is not a good fit." I've been working with customer service, but they won't reactivate the account I never even signed into once and won't give me any reason. I understand that they can't divulge how their security measures work, otherwise spammers could circumvent them. But still... There's gotta be a better way. Frankly, I was pretty soured by the experience.

Worst experience ever. better to try direct API, or use other services. I used paid services. as soon as i used my card. provided everything. now they are also asking me the color of the underwear i was wearing when i deposit the amount. 10000% scammers. don't waste your time.

Twilo Ireland phones are the source of persistent unwanted spam calls.

When reviewing my cellular call logs I often see Twilio as the originator of many unsolicited scam calls. I just want them to know I will block every Twilio number until they cease to facilitate such behavior, or go out of business.

I signed up for Twilio to evaluate it for potential business use with my company. I never even got the chance to log in — my account was instantly suspended right after sign-up. No explanation, no human verification, just an automated accusation of “irregular activity.”

I replied with all requested information, including my company website, but received a generic response saying my “use case is not a fit” and that the decision came from automated systems that support staff can’t override or explain.

In short:

New account → immediately banned

No access, no activity, no reason given

No human review possible

For a company that builds communication tools, Twilio seems incapable of communicating with its own users. If you’re a legitimate business trying to test their services, expect to be treated like a fraudster by a bot.

This is hands-down the most frustrating onboarding experience I’ve ever had with any SaaS provider.

Twilio - phoning from an 0161 number. Unwarranted spam call, and they're persistent: Block Them.

The worst experience on the entire web, extreme unprofessionalisme, if you want to waste time, efforts, money, and YOUR DATA!! try Twilio.

- They Required so many things including some very sensitive infos, multiple times on email, and for no reason, after adding money to my account they suspended the account, extreme SCAM!! i don't know why this website is still operating??

I paid the initial $5 and got nothing out of it (referred through another agent Telfon). There was supposed to be a 14days free trial. Even then it was difficult to cancel the order. Not a single phone call. It does not work at all. It is a scam.
The support seems like they are helping you to get connected and stuff, but it's all a scam.

Coming from a once inside source, this company is deeply flawed—hiring terrible people, delivering poor service, and firing the good, hardworking employees because of personal feelings and gender bias. This company feeds the egos of assholes who don’t need it. It is sexist toward men, with an underlying hint that it’s somehow acceptable to be sexist because they’re men. From one woman to another, I am disappointed—disappointed that you have the nerve to hate on someone because of their sex, knowing full well that if the situation were reversed, people would be outraged. Flipping the bias onto the other gender is complete bullshit, and I am beyond disappointed. Find business elsewhere unless you enjoy giving assholes your money.

They use Amazon Inc servers and they were hacked from their own servers.

All integrations flagged with account takeover restrictions with no resolution in sight.

We have thousands into fixing issues from Twilio/Sendgrid from our engineer.

No support, no service, no way to close account with account takeover.

This has to be the worst company I have yet to encounter in software development.

Banned My account The moment I deposited money ,poor customer service, late replies everything about this company sucks better use other providers Its not going to go any worse

I have been receiving calls from this company and I keep blocking them, but they just use another number. I think this company should be closed down, as they don't provide anything useful and in general ,they are a pain to the general public by continually phoning people up.

On October 10, 2025, our Twilio account got compromised. In about an hour, fraudsters ran up over $5,000 in charges through nonstop auto-recharges. Twilio flagged it and suspended at ~00:18:58 UTC on October 11, but the damage was done. Now, they're demanding we pay an extra $3,829 negative balance on top of the $5,128+ they already pulled from our Visa—total hit nearly $9k for stuff we didn't do.
We've secured everything (rotated keys, enabled 2FA, deleted projects to start fresh) and sent a Root Cause Analysis, but Twilio's response? Blame us per TOS, offer a vague "partial courtesy credit" (no amount given, subject to Finance), and say pay up or the account stays suspended. Based on other stories here, these partials are usually crap—like 20-50% if you're lucky.
The real issue: Twilio's "budget" system (prepaid + auto-recharge + usage triggers) isn't a hard cap. Triggers just notify; auto-recharge keeps funding the fraud; delayed billing adds more post-suspension. No native limits mean one key leak = unlimited exposure. This isn't rare—search this sub or BBB/Trustpilot for $1k–$30k horror stories from SMS/voice pumping via overseas IPs (ours was UK-based 81.156.***).
New updates: Support keeps pushing TOS and "your side exposed credentials," ignoring how their design enables escalation. We've demanded a full reversal and hard caps ("stop-at-$X" or true $0 halt with bounded drift), but no dice. Twilio admits rising takeovers in 2025 but puts all prevention on users.
We're posting to warn everyone: This could wreck any dev or startup. One compromise away from bankruptcy. Demanding change: full refund for us and real spend caps for all.
If you've dealt with Twilio fraud/overcharges, we'll compile anonymized stories for awareness/maybe group action.
Quick Protections (Since Twilio Won't):

Kill Auto-Recharge: Go true prepaid—stops at $0 (watch for billing drift).
Geo-Permissions: Lock to needed countries.
Kill-Switch: Trigger webhook to auto-suspend subaccounts (code gist: [link – create one with your example]).
Bank Side: Virtual card with daily limits.

Stay safe out there. #Twilio #FraudWarning #DevLife #CloudBilling

The "port a number feature" is broken, and they want me to pay to get their support to fix it. Probably going to chargeback if they don't get back to me soon. Sucks, seems nice IF it wasn't broken.

I wish I read these reviews before using Twilio. We were inexplicably charged 20X our usual monthly amount - they have no explanation and are now refusing to reply to our support ticket asking for a refund for that month.
They have literally taken our money and now not speaking to us - is this really a business?
