We support sending SMS to industries in over 200 countries worldwide, excluding mainland China.

Log in to the client, complete authentication, select "Send SMS," and choose between fixed or dynamic SMS sending. Detailed steps can be found in the operation document on the client.

Reconnection and testing are not required, but business binding with staff is necessary.

The format should be country code + mobile number. Both "+" and "00" are acceptable as we handle the prefix. For example, for the Philippines (country code 63 + number 955*6041, 63955*6041).

Special characters such as ￥, ★, _, &, √, ※, etc., are not supported and may cause SMS to appear garbled.

There are no time restrictions for sending verification and notification SMS. Promotional SMS can only be sent between 8:00 AM and 9:00 PM in most countries to avoid user complaints. Some countries have no such restrictions.

MMS and SMS with links are supported.

• Links may appear as plain text if they are connected to the text. Add spaces before and after the link or a colon before the link and resend to see if it displays as a hyperlink. (Ensure to use English symbols, as Chinese symbols may affect SMS character count.)
• Log in to the client, click "Send SMS," select "Send Records," and view SMS success rates and records.

SMS sending records are stored for up to six months, and message receipts are supported.

Check if the number format is correct (including the area code). If the number is correct, contact customer service for account adjustments.

No, services within mainland China are not currently supported.

The content may not be compliant (local operators prohibit certain SMS content).

• Analyze from the following aspects:
• 1. Was the sending successful?
• 2. Is the link valid (can the destination country's network open it)?
• 3. Is the number valid?
• 4. Is the sending time during normal activity hours in the destination country?
• 5. Is the content attractive?

Pricing varies by country. Contact customer service for a dedicated staff member to assist you.

  • Signature Example: SMS signature "signaturesignaturesignature," calculated as 9 characters
  • Template Variables Example: A template variable "${1}" (other number), with a value of "123456," calculated as 6 characters; the default maximum value is used when applying for the template, and the final value is based on the actual sent variable value.
  • Other Symbols Calculated as 1 character
  • Non-English Characters (including punctuation) The SMS is calculated as other language SMS in length; please choose the text format carefully. -


• The SMS template character limit is 500 characters, meaning the maximum length of a single long SMS = SMS signature + 500 characters.
• When sending long SMS, users will ultimately receive one long SMS, but the SMS business platform will count and charge based on the number of split SMS.

There is no notification for account credit running out, but customers can set up email reminders when the balance falls below a certain value.

Contact staff for timely top-up. Failure to top up promptly may affect subsequent business operations and company/personal credit.

Contact staff or customer service for assistance.

• 1. Online top-up: Log in to the client, click "Top-Up," and select your preferred method.

Online top-ups are immediate, while other methods may have a 1-2 day delay.

PayPal top-up is generally not open. If you need to use PayPal, apply to staff and complete identity verification to prove that the PayPal account is used by you.

The payer bears the fee.

• Credit is the credit limit, which is the amount customers can use for post-payment. Eligibility and amount of credit need to be applied for with staff and are not available amounts or balances.
• Available amount = balance + credit + gift amount.

• 1. When the sending status is "Submission Successful (delivery)," it is charged. Even if the status returns as "failed," it is charged, according to the "send and charge" rule set by international/Hong Kong, Macau, and Taiwan operators.

• 3. Check if the mobile number is correct, if the signal is good, and if the phone is turned on.

• 2. Modifications are allowed, and applications can be submitted to staff.

The display number needs to include the country code to show the incoming call number correctly. Otherwise, a random display number will be shown.

Country code + mobile number. For example, for the Philippines (country code 63 + number 955*6041, 63955*6041).

The calling format is country code + local number, such as an Indian number 91740828XXX, where 91 is India's country code, and 740828XXX is a local Indian number. Enter the complete country and local codes.

The display number is set incorrectly, or some countries have restrictions on display numbers.

Check the local country's operating strategy; some countries allow fixed display numbers, while others require random display.

We have our own number pool, and fixed numbers have multiple options to prevent interception.

• Enter the number to call, either by clicking on the number keys or copying it on the computer.

Check the number dialing format; the phone's call format is country code + local number, such as the Indian number 91740828XXX, with 91 as India's country code, and 740828XXX as an Indian local number. The call format is 91740828XXX.

Check for network issues and reopen.

Calls are charged after connection. Manual seat billing is 60+60, i.e., per minute; group call billing is 20+20, i.e., every 20 seconds. Contact staff for detailed information. Quotes are uniformly based on minutes.

The billing cycle is the unit of measure for call duration, in seconds. If the call duration is not a multiple of the billing cycle, the cost is calculated based on an additional billing cycle.

Each phone call record contains a recording file, which users can download and store locally.
