Reasonable Use Policy

This Reasonable Use Policy (“Policy”) is hereby presented by Iristel to its Customers as a guide to understand the intended and permissible use of Service and to prevent exploitation, fraud and abuse of its Services. This Policy may be subject to change from time to time and the revised copy is effective immediately upon posting to www. iristel.com. 

1. Prohibited Uses, Spam 

The Customer agrees to use Service solely for lawful purposes. Services cannot be used for: 

a) Transmitting or receiving any illegal, harmful, threatening, abusive, harassing, defamatory, obscene, sexually explicit, profane, racially or ethnically disparaging remarks or otherwise objectionable material of any kind. This includes, but is not limited to, any material that encourages conduct that would constitute a criminal offence, give rise to a civil liability, or otherwise violate any applicable local, state, provincial, national or international law. Customer acknowledges full responsibility for any and all voice traffic emanating from his/her/its device, authorized or otherwise. 

b) Unauthorized manipulation or alteration of Automatic Number Identification (ANI). Calls must originate from Customer’s assigned Iristel numbers within the provided trunk, and the caller ID must correspond to one of these numbers. Customers are explicitly prohibited from engaging in any activities, such as caller ID spoofing or identity theft, that involve the intentional modification, suppression, or falsification of ANI for deceptive, fraudulent, or malicious purposes and any such activities shall be considered in violation of the terms and conditions governing the Service and this Policy. 

c) Auto-dialing, continuous or extensive call forwarding, telemarketing, fax or voicemail broadcasting or fax or voicemail blasting.

d) Transmitting text messaging spam, bulk unsolicited messages, unwanted telemarketing, promotional or informational messages, or any other form of unsolicited electronic communications without having procured the necessary consents, right and license from the recipients of such messages. Customer is solely responsible for obtaining all necessary and appropriate rights, licenses and consents from those person(s) and entity(ies) with whom Customer messages or otherwise communicates with via the Service, prior to commencing any such messaging or communication. Additionally, Customer shall not use the Services to send unwanted messages to any individuals who have asked to stop receiving messages through any medium. To the extent required by applicable law, Customer must track and record all such requests. Customer must also provide recipients of MMS/SMS messages with clear notice of their ability to opt-out from receiving any future text messages, by texting STOP in a stand-alone message with no additional characters or punctuation. Without limiting the foregoing, Customer shall not i) use the Services for, or in connection with sending pyramid schemes, chain letters, any mail in contravention of applicable law, altering or obscuring mail headers or assuming the identity of a sender without the explicit permission of that sender, ii) advocate, encourage or assist any third party in doing any of the foregoing activities in this Section. 

Customer agrees to promptly cooperate with Iristel in any investigations to identify potential sources of illegal traffic and/or material, and shall otherwise take steps to combat the origination of any such traffic and/or material.

2. Excessive Service Use

Iristel may consider excessive the use of Service where Customer exceeds the average client-base usage patterns, reasonably determined by Iristel from time to time upon a network usage analysis, in conjunction with other factors that can adversely impact other Iristel customers or the Iristel network. 

Voice plans, including those marked as “Unlimited”, are subject to an aggregated monthly use limit of 3000 minutes. 

Internet plans are subject to a monthly data limit of 500 GB for business users and 300 GB for residential users. Iristel may also consider excessive use of its Internet Service any circumstance where the Customer is running an application that places excessive bandwidth demands. 

3. Violation of this Policy 

If Customer is in violation of this Policy, Iristel reserves the right to take immediate corrective action, without advance notice, as necessary in Iristel’s reasonable opinion, including but not limited to suspension or termination of the Services, legal action, or reporting illegal activities to the relevant authorities.  

The failure of Iristel at any time to enforce any provision of this Policy in any one instance shall not constitute a waiver or relinquishment of any such provision as to any other instance, and the same shall continue in full force and effect.

WIRELESS REASONABLE USE POLICY

You may use the Services only for your own lawful purposes. We may from time to time set out use policies and guidelines for the use of Services. Services cannot be used for transmitting or receiving any illegal, harmful, threatening, abusive, harassing, defamatory, racially or ethnically disparaging remarks. This includes, but is not limited to, any material that encourages conduct that would constitute a criminal offence, give rise to a civil liability, or otherwise violate any applicable local, state, provincial, national or international law.

We have built our network around sustaining high-speed data services; however, in times of network congestion, to ensure the best service experience for the majority of our customers, we reserve the right to prioritize the allocation of network resources to customers whose usage is below 10GB in a given month for satellite-served home network locations, below 20GB for non-satellite-served home network locations, or below 4GB while roaming outside the Iristel Wireless home network. There may be other factors such as weather, signal strength, device capabilities, technical limitations, or outages that could affect your data speed.

You must note that the service is provided for regular commercial and/or residential use only and we reserve the right to suspend or terminate the service if you are in breach of any use policies.

IRISTEL SMARTER MESSAGING — FAIR USE POLICY

Last Updated: October 2026

All capitalized terms used without definition have the meanings set forth in the Iristel Master Services Agreement or Terms of Service (“Terms”), which are incorporated by reference. This Fair Use Policy supplements but does not replace the Terms. Iristel reviews and updates this Policy on at least an annual basis.

1. PURPOSE

This Fair Use Policy establishes usage limits and standards to ensure equitable access to the Smarter Messaging powered by Clerk Chat services (the "Services") for all Iristel customers, protect network integrity and message deliverability, and maintain compliance with carrier policies, The Campaign Registry (TCR) requirements, and applicable law including the TCPA, CRTC regulations, and FCC/telecom regulations.

2. DEFAULT USAGE LIMITS

2(a). Standard Plan Limits

Unless otherwise specified in Customer's Order Form, the default limit per team per calendar month is:

• SMS/MMS Messages: 120,000 outbound segments (Note: Voice minutes are not included under this messaging-only policy).

The first month of service is prorated based on days remaining in the activation calendar month.

How segments are counted: Usage is measured in message segments, not messages sent. A single SMS segment holds up to 160 characters using GSM-7 encoding, or up to 70 characters where the message contains any UCS-2 character (including most emoji, curly quotes, and non-Latin scripts). Longer messages are automatically split and sent as multiple concatenated segments — 153 characters per segment for GSM-7, 67 for UCS-2 — and each segment counts against Customer's monthly limit and is billed separately. Links, merge fields, signatures, and required opt-out language all count toward the character total and may push a message into additional segments.

2(b). Channel-Specific Limits, Notes, and Compliance Requirements

• RCS (Rich Communication Services): RCS usage is billed and limited separately per the Order Form. Customer must comply with applicable RCS Business Messaging Acceptable Use Policies. RCS consent requirements may differ from standard SMS/MMS consent standards; express opt-in consent from each recipient is required before sending any RCS business message.
• WhatsApp Business API: WhatsApp usage is billed separately. Customer must comply with Meta's WhatsApp Business Policy, including WhatsApp-specific opt-in requirements. Consent obtained for standard SMS does not constitute consent for WhatsApp. Marketing messages outside a 24-hour customer service window require WhatsApp-approved Message Templates.
• AI Text Agent Interactions: AI text agent interactions may have separate usage caps per the Order Form. All automated messaging must comply with applicable telemarketing and electronic commerce laws (such as TCPA and CASL).
• International Messages: Not included in the 120,000-segment default limit; charged separately at then-current international rates.
• API Usage: Subject to rate limits published in API documentation.
• SHARED SHORT CODES — ABSOLUTE PROHIBITION: Iristel does not support and expressly prohibits the use of shared short codes (short codes used by multiple brands). All short code traffic must be on dedicated short codes registered exclusively to Customer. Violation of this prohibition is a material breach of the Terms of Service and grounds for immediate termination.

2(c). Custom Plans

Enterprise and mid-market customers on custom Order Forms operate under the limits in their individual agreements. Section 2(a) defaults do not apply to customers with Order Forms that expressly state different limits.

3. 10DLC THROUGHPUT LIMITS AND PRE-APPROVAL REQUIREMENT

Regardless of plan volume limits, Customer must comply with carrier throughput requirements:

• 10DLC Long Code (A2P SMS): Throughput limits are defined by TCR campaign scoring and carrier guidelines, typically 15–75 messages per second depending on campaign type. System rules enforce these limits programmatically.
• PRE-APPROVAL REQUIREMENT — CRITICAL: Customer may not send A2P SMS traffic on a 10DLC number until TCR has confirmed campaign ACTIVE status — submission alone does not authorize traffic. Iristel will use technically reasonable means to prevent transmission on campaigns in pending or submitted status. TCR standard reviews typically take 2–5 business days; special use cases may take longer. Customers and partners must not plan campaign launches within less than 5 business days of campaign registration submission and must confirm ACTIVE status before launch.
• Toll-Free Numbers: Subject to carrier-imposed throughput limits.
• Dedicated Short Codes: Throughput governed by the applicable carrier agreement.

Attempts to exceed carrier throughput limits — including through batching designed to circumvent filtering — are prohibited and may result in immediate account suspension.

4. PROHIBITED USAGE PATTERNS

The following usage patterns are prohibited regardless of volume, as they violate carrier AUPs, 10DLC rules, or applicable law:

• Sending messages at uniform intervals at high volume designed to evade carrier spam detection;
• Sending identical or near-identical content to large recipient lists without a registered campaign;
• Transmitting campaigns generating opt-out rates above 5% or complaint rates above 0.3%;
• Recycling or reusing recipient lists containing previously opted-out numbers;
• Sending messages outside permitted hours (in accordance with local jurisdictional regulations, e.g., 8 a.m.–9 p.m. local time);
• Transmitting A2P messages on numbers not associated with an active, TCR-APPROVED campaign (submission pending is not ACTIVE);
• Characterizing functionally A2P traffic as P2P to avoid 10DLC registration — this is carrier fraud and a material breach of the Terms;
• Sending messages to telephone numbers identified as reassigned by registries after the date of the original opt-in consent;
• Using shared short codes under any circumstances.

5. MONITORING AND OVERAGE

5(a). Usage Monitoring

Iristel monitors messaging volume, delivery rates, opt-out rates, complaint rates, and campaign registration status on an ongoing basis. Customers can view current usage in their portal dashboard. Dashboard usage figures are reported in segments.

5(b). Overage Notification

Where commercially reasonable, Iristel will notify Customer when usage approaches the applicable monthly limit (at approximately 80% and 95%) via email or in-app notification.

5(c). Overage Charges

If Customer consistently exceeds monthly limits (in two or more consecutive months), Iristel may: (i) assess overage charges at then-current per-message rates; (ii) require Customer to upgrade to a higher-volume plan; or (iii) suspend transmission above the limit.

5(d). High-Volume and Special Use Case Campaigns

Customers planning campaigns expected to exceed standard monthly limits, or campaigns in special TCR use cases (political, higher education, emergency, sweepstakes), should contact support in advance to ensure proper provisioning, accurate TCR registration, and realistic launch timelines.

6. QUALITY STANDARDS

To protect deliverability for all users, Iristel enforces the following quality thresholds:

• Opt-out Rate: Campaigns generating STOP rates above 5% may be paused pending review.
• Complaint Rate: Campaigns generating carrier complaint rates above 0.3% may be paused pending review.
• Delivery Failure Rate: Persistent delivery failure rates above 20% may trigger campaign review.

Iristel will notify Customer of quality threshold breaches and work with Customer on remediation before taking action where time permits, but reserves the right to immediately suspend campaigns posing a risk to carrier relationships or platform deliverability.

7. CARRIER-INITIATED BLOCKING — NO IRISTEL LIABILITY

Carrier-initiated blocking is one of the most common operational disruptions for messaging users. Carriers block campaigns unilaterally and without notice, and Iristel has no control over carrier decisions.

Iristel is not responsible for message delivery failures caused by carrier-initiated filtering, blocking, or de-registration of Customer's campaigns. Carriers (AT&T, T-Mobile, Verizon, Rogers, Telus, Bell, and others) may block campaigns based on their own spam and compliance algorithms without prior notice. Iristel will make commercially reasonable efforts to notify Customer of known carrier blocks where notification is received and work on remediation where technically feasible, but cannot guarantee restoration. Customer is responsible for maintaining compliant campaign registrations, accurate message content, and low opt-out and complaint rates to minimize risk.

8. ENFORCEMENT

Violations of this Fair Use Policy are subject to enforcement under the Terms:

• First violation: Written notice and 5 business day opportunity to cure.
• Second violation within 12 months: Written notice, mandatory remediation plan, possible temporary suspension.
• Third violation within 12 months, or any violation involving TCPA, CASL, carrier-level blocking, or unauthorized A2P traffic on unapproved campaigns: Account suspension pending review; possible termination.

Pre-Approval Blocking: Campaigns submitted for TCR registration but not yet approved are NOT subject to notice and cure provisions. Iristel will block transmission on pending campaigns without notice or cure period. Upon TCR ACTIVE status confirmation, normal campaign operations resume.

Immediate action without notice may be taken where required to protect the platform, other users, or compliance with applicable law or carrier mandates.
