activ (Kazakhstan) — how to reach customer service and get fast resolution

Official contact channels and where to find the phone number

The single most reliable source for activ customer service phone numbers is the operator’s official website: https://www.activ.kz. Official short-codes and international support numbers are maintained there and updated when tariffs, working hours or routing change. If you are unsure about a number you have found elsewhere, cross-check it against the contact page on activ.kz before sharing personal data.

From an activ mobile the operator commonly provides a short customer service code (check the site for the exact active short-code). For calls from outside Kazakhstan, you must use the international support number listed on the site and dial Kazakhstan country code +7 first. Using the official site avoids scams, spoofed customer-service numbers and cost surprises.

How to call: local, international and roaming cases

Local calls from an activ SIM: use the short-code provided on the website (short-codes are billed at in-network/minimal rates). If you are on another Kazakh operator and need to contact activ about porting, billing or a complaint, use the international-form number from activ.kz or get assistance via the online complaint form on the site.

Calling from abroad: dial +7 (Kazakhstan) then the full number printed on the activ contact page. Do not rely on third-party directories for international numbers — rates vary and roaming restrictions can block short-code dialing. If you have roaming issues, request an international support line specifically marked for roaming customers; that line will accept calls from foreign networks and provide ICCID/SIM guidance.

In-person support: stores, documentation and typical service fees

activ maintains branded retail stores and authorized dealer outlets in all regional centers (for example Almaty and Nur-Sultan / Astana). Store addresses and opening hours are listed on the “Stores” or “Service Centers” section of activ.kz. For SIM replacement, number transfer (MNP) and identity verification you should bring your national ID or passport; non-residents must present a valid passport and migration registration if required by local law.

Typical transactional fees (estimates): SIM replacement or reissue is usually a small one-time fee (commonly in the range of a few hundred to a couple of thousand Kazakhstani tenge — KZT); tariff activation or on-the-spot plan changes normally take effect immediately and may require top-up. Always ask the retail agent to show the current printed price list; keep receipts for any change so you can escalate if necessary.

What to have ready when you call customer service

Prepare these items before calling to speed up resolution: your full mobile number (in international format +7 X XXX XXX XXXX), your ICCID (SIM serial) if available, account holder name, date of birth, and the last 3 top-up transactions or invoice amounts for verification. If calling about billing or fraud, note the exact date/time of the incident and any SMS/call details.

If your issue is SIM-related (lost SIM, stolen phone, or SIM cloning), request immediate SIM lock or suspension and ask for an incident/ticket number. Ask the agent for expected resolution time (for example: immediate block, SIM replacement within same day at a store, or fully restored service within 24–72 hours depending on case complexity).

Escalation, complaints and how to document your case

If the frontline agent cannot resolve your issue, request escalation to a specialist or to the “Quality/Complaints” department and obtain a written ticket number and the agent’s name. Note the timestamp and the expected SLA (e.g., “resolved in 3 business days”). If your complaint is still unresolved after the stated SLA, escalate with a written complaint via the website’s complaint form and copy the reference number into any future correspondence.

Keep a file with the following: screenshots of error messages or SMSs, receipts and invoices, the complaint/ticket numbers and names of staff you spoke to. If you need to bring the matter to a regulator, this documentation will be required to support your claim and accelerate enforcement.

High-value quick-reference list

• Official website (primary source for numbers and stores): https://www.activ.kz — always verify numbers here before calling.
• From abroad: dial +7 then use the international support number shown on activ.kz (short-codes rarely work from foreign networks).
• What to bring to a store for SIM reissue: national ID or passport, proof of ownership (receipt or last bill), and the affected handset if requested for diagnostics.
• When calling: provide your full number in +7 format, ICCID (if available), and the last 3 transaction amounts for identity verification.
• If suspicious of fraud: ask the agent to immediately suspend the SIM and issue an incident ticket — record that ticket number.

Practical tips to speed resolution

Use the web-chat or social media channels listed on activ.kz for non-urgent requests — chat transcripts produce a written record and often transfer faster to specialists. For billing disputes, raise a written complaint and attach scanned receipts; verbal promises are difficult to enforce without the ticket number. For technical network problems, record exact time, location (city and street) and device model — these data help engineers reproduce and resolve outages more quickly.

Finally, always confirm follow-up times and keep the ticket number. If you need written confirmation (e.g., for porting or contractual changes), ask the agent to email you a copy of the change. That prevents misunderstandings and provides a clear audit trail if you must escalate to a regulator or consumer protection service.
