The text message alert for the WiFi Authentication & Billing system in the park is not simply a validation code, which runs through the entire life cycle of user registration, payment, maturity, and flow warning. It is well-sented, users experience an increase in, and fall in rates; it is bad, users feel harassed or even complain to operators. The core of the text message notification is that it is given at the right time, with the right content, to the right person, neither leak nor misdirected.
Which scenes must be texted?
The first category is related to authentication: the authentication code when user SMS registers, the security alarm when passwords are replaced, and the security alert when login abnormally. Such messages are functional, must be sent quickly, and require a five-second time period for delivery of the SMS. The second category relates to contributions: notification of successful payment, notice of automatic renewal fee deductions, notification of failure of payments. These texts are documented and require confirmation of withholdings and service openings. The third category is classified as reminders: reminders of renewals three days before the month expires, 80 per cent and 95 per cent of traffic alerts by stream users, and inadequate balances. The fourth category is notification: notice of system maintenance, price adjustment, and notice of park activity.
Principles for designing text messages templates
SMS templates should be simple, clear and action-oriented. A text message does not exceed 70 words (longness of a text message), exceeding multiple lines, with increased costs and poor experience. Template structure: call + matter + key information + action guidance + dropout. For example, alerts due:"[Worm Park] Your WiFi package expires on August 31, and the link renewal fee is clicked.". Key information should be specific: due date, amount of outstanding fees, remaining flow, not just"Your account is about to expire."The action directions are clear: a renewal link, a call to the client, and an address to process. The name of the place must be given before users know who sent it.
Control of the dispatch frequency
SMSs are most dangerous to bomb. The same user receives multiple text messages within a day, and even pulls black numbers. Frequency control rules: only one message with the code number in 60 seconds, up to five times within an hour, preventing malicious scissors. Time-expiring reminders: 1 message before expiry three days, 1 message before maturity, up to three times on expiration, not sending daily. V7 can configure the maximum daily text distribution limit for each user, and it is not sent again after this time."TD"Resetting of operational type SMSs, but functional SMS (certification code, certificate of contribution) cannot be re-subscribed.
SMS Channel Selection and Backup
SMS channels have a direct effect on the delivery rate and speed. Business-level text message service supports the formal messaging service provider that starts with 106, which has over 95% of the service flow through the company ' s messaging channel and is delivered within 5 seconds by the authentication code. Do not use personal text message cat or grey passages, which are low and may be intercepted by operators. SMS channels need to be prepped for two main access routes, automatically switch to backup channels when the main channel fails, avoiding failure to send the authentication code from being registered to users. V7 supports third party SMS platforms, sends messages via API interfaces, and can configure two main channels that fail to retest the backup channel automatically. SMS service delivery rates are also monitored, and alerts are reported at less than 90 per cent of cases and timely contact with the service provider for screening.
Control of SMS costs
SMSs are billed by bar, and the campus has a large number of users at no lower cost. Cost control methods: First, shortest templates for authentication code text messages are used to keep them within one line. Second, reminders send together, such as expired alerts and traffic warnings, if they trigger on the same day. Third, non-emergency notifications replace text messages with APP or micro-letter public messages, which are less expensive. Fourth, capping each user per month, exceeding the later notification method. Fifth, talking to SMS providers about step prices, which is lower than the unit price. SMS costs are factored into operating costs, monthly text messaging and cost counts, analysis of which scenarios have the greatest delivery capacity and whether there is room for optimization.
Failed to send a message
The text message is sent for many reasons: the user's cell phone number is down, empty numbers, SMS channel is out of order, content is intercepted."Could not close temporary folder: %s", and provide voice-validation options. When a reminder text message is sent unsuccessfully, the system records a failure log, the next opportunity to send it up, or a page alarm when the user logs in again. The V7 system records the sending status of each text message (success/failure/to be sent), which allows the administrator to query the failure record and manually re-enact the number. It also regularly cleans the invalid cell phone number, verifies the validity of the cell phone number at the time the user registers, and the user tags the downed or empty number are invalid and no more text messages are sent.
Compliance and privacy
SMSs are personal and personal. First, users register to clearly inform the user of their cell number use (certification, fee alerts, notification) and obtain user consent. Second, a mobile phone number cannot be provided to third parties for marketing purposes. Third, text messages cannot contain sensitive information (complete password, identity number), and are certified code type text messages indicating their validity. Fourth, records of SMS send are kept for at least six months for audit purposes. Fifth, they are subject to the Personal Information Protection Act and the Short Messages Service Regulations, and commercial text messages may not be sent without user consent.
The center of the text message alerts for the campus WiFi Authentication & Billing system is full coverage and frequency-free access. The full scope of the warning on registered contributions due to non-intrusive traffic is backed up. The template has a clear action guide, with a ceiling on daily delivery, automatic switchover of main backup channels, optimization of monthly costs, failure of sending, retesting and rollout, personal information compliance.
