The carrier associated with this phone is not supported

ChatGPT

I am trying to signup from South Africa however my phone number is not being accepted. The message displayed after entering the number is “The carrier associated with this phone is not supported. For help, contact us through our help center at help.openai.com.” This is a valid cell number which is in use, not a VOIP or landline. How does one resolve this?

Thank you for your response. I have not found a solution as yet. Have you?

No, I am unable to contact ChatGPT for any information on why my phone cannot be verified. I can only reach the bot which directs me to a help page but which does not give me any idea on what is preventing my phone from being verified. I have tried using different number formats (+6018xxxxxxx, +60018xxxxxxx), sms, whatsapp. I can sign-in using my email and password but it fails after “Verify your phone number”

Today, I reported the matter to my mobile phone service support team. They informed me that everything in order at their (network) end and that I should contact ChatGPS to know the problem. So it is just hanging there… hope we can get a solution to this problem

I’m from Malaysia. I’ve encountered the same problem too and I’m using UMobile. I don’t know why it shows like this “The carrier associated with this phone is not supported”. I hope the ChatGPT support team will help us to solve the problem.

Hi,
I am not OpenAI staff member. But let’s see if I can help you in any way.

From March 2023 until now, OpenAI has undergone intense changes, mainly with regard to security, including the hiring of Cloudflare for this area.

There are several symptoms when signing up for a new account:

  1. Your account has been flagged for possible abuse: Happens most often in
    1.1 Unsupported Countries - unresolved.
    1.2 Supported Countries - related to email reliability, browser reliability, and IP address already used - solution found.
    More details and solutions at: Your account was flagged for potential abuse ;

  2. Looks like this is a virtual phone number (also known as VoIP): So far it has only been detected in Canada (Supported Country). No solution so far.
    More details at: My phone number is not a VOIP! ;

  3. The carrier associated with this phone is not supported: so far only detected in Supported countries (non-US) - this thread;

The mobile/cell phone is only used to send SMS with the confirmation code for opening a new OpenAI account. It is normally not flagged - and may continue to be used when opening a new account, because

  • IP is temporarily flagged - must be changed;
  • The email is flagged… forever - another one should preferably be created on Google (@gmail.com.xx) and Microsoft (@outlook.com.xx, @hotmail.com.xx) domains. These two domains have a security/id verification service (one password for everything), and new users must sign in using the Google/Microsoft account.

Here in the forum, there are some who are suspecting that 2. VOIP and 3. Unsupported carriers are just justifications - and may be more related to some phone brands and software from Unsupported Countries.

What we can do is spot the coincidences as everyone in this thread seems to be from Supported Countries with different legitimate carriers.
Then describe what is possible for sign up:

  1. DO NOT PUT YOUR PHONE NUMBER HERE;
  2. Phone brand (Apple iPhone, Huawei, Samsung, etc.):
  3. Your active carrier service (3G, 4G, 5G, LTE, VoLTE, etc.):
  4. Any active messaging service/product (iMessage, FaceTime, etc.):
  5. Any software from Unsupported Countries on phone or computer (ad blocker, antivirus, Tik-Tok, etc.):
  6. Computer browser (Chrome, Edge, etc.):
  7. Any VPN service or hidden VPN under antivirus:
  8. Email domain (@abcde.xx):
    DO NOT PUT YOUR FULL EMAIL HERE

And we can check what coincides as the cause of some of these problems.

Same problem here! In Malaysia, apparently the issue is with U Mobile. The ones I;ve read are from this same phone operator, and I have friends that have another operator and can use it no problem. So PLEASE if you find out the solution and please let me know.

I’ve been trying the same from here with a Spanish Phone number… and also…NOTHING!!!

That is why more data is necessary - so we can all check what is happening.
This is not happening with all users from the same country, same carrier, etc. Otherwise, this forum was flooded with these complaints.

So far… (in this thread, and VOIP thread)
Non-US Supported Countries: Canada (VOIP - most of the carriers), South Africa (Cell C), Malaysia (UMobile), Spain (?);
Carriers: Cell C (za), UMobile (my);
Brands: Huawei;

There is not so much data yet - one important thing is the carrier service - are you using 5G? On a phone brand from unsupported country?
The Huawei+5G pair, for example, have a higher probability of failure(??)

Try help.openai.com once more.
Mr. Logan Kirkpatrick (OpenAi staff) advised the Help Desk is in full service now.

The only thing we noticed is that the Carriers: Cell C (za) and U Mobile (my) have small LTE options on bandwidths

MCC MNC Brand - Country
Operator - Status
Bands (MHz)
655 07 Cell C - South Africa
Cell C (Pty) Ltd - Operational
GSM 900 / GSM 1800 / UMTS 900 / LTE 1800 / LTE 2100
If you are trying with LTE on - turn it off (go to GSM), and try again.
If you are trying with LTE off (it was on GSM or UTMS) - turn it on, and try again.
If none of these options work: install a SIM2 card (Vodafone, preferably), open a free account, and receive the SMS confirmation code - DO NOT fill in any bank or credit details until this problem is definitively resolved.

502 18 U Mobile - Malaysia
U Mobile Sdn Bhd former Mobikom - Operational
LTE 1800 / LTE 2100 / LTE 2600 / UMTS shut down Dec21
Domestic Roaming with Maxis, also for GSM;
See below:
502 17 Maxis - Malaysia
Maxis Communications Berhad Former TimeCel, Adam017 - Operational
GSM 900 / LTE 1800 / LTE 2100 / LTE 2600 /UMTS shut down Dec21
If you are trying with LTE on - turn it off (go to Maxis GSM), and try again.
If you are trying with LTE off (it was in GSM roaming) - turn it on, and try again.
If none of these options work: install a SIM2 card (Celcom Axiata, preferably), open a free account, and receive the SMS confirmation code - DO NOT fill in any bank or credit details until this problem is definitively resolved.

Please, let us know.

Additional information:
How to change carrier service - may vary by phone brand and model
On the phone:
Settings >> Connections >> Mobile networks:
Turn off (or on): LTE or VoLTE options for the specific SIMx card.
Also, in Network mode SIMx: (default: auto-connect) choose one of the options according to the testing you are performing (with/without LTE);
Choose 4G or 5G if they are available in your area, only.
After you receive your SMS confirmation code, you can set back your previous settings.
