Once upon a time, in the drawer of her study desk, lay a dozen SIM cards from various providers. Some hadn't been touched in three years, others were bought brand new but immediately forgotten because the numbers didn't match. Dina Maheswari, a fifth-semester student at Sebelas Maret University, Solo, never imagined that a pile of small plastic cards would one day become the "raw material" for her primary source of additional income.
Now, Dina manages five WhatsApp Business accounts and three Telegram accounts, each connected to a different number. All these numbers weren't newly purchased. They all came from her own old SIM cards that she "reactivated" in a much cheaper way than buying new virtual numbers from the marketplace. "It started as a whim, then it turned out to be possible," Dina shared when her method was first shared in an online business student group.
From Forgotten Drawer to Valuable Resource
It all began with a practical need. Dina runs an online business selling K-pop albums and merchandise. To build customer trust, she needed to separate her personal number from her shop's number. The problem was, buying new SIM cards with continuously active plans incurred significant monthly costs. Top-up credit, internet package fees, all added up every month.
This is where Dina's clever idea emerged. Instead of buying new numbers, why not utilize the existing SIM cards? Especially those whose validity period had expired but the number and registration were still active in the operator's system? In other words, cards that could technically still receive OTPs for certain services.
This method has actually been known for a long time within the virtual number user community. Many thought old SIM cards were definitely "dead" once their active period ended. In reality, as long as the number hasn't been re-registered by someone else or permanently blocked by the operator, these cards still hold great potential for use as verification numbers.
Step-by-Step: How to Create "Nokos" from Old SIM Cards
Here's the process that Dina successfully implemented and has now been adopted by dozens of members in her community:
First, identify and sort the cards. Dina collected all the SIM cards she had bought over the past three years. She separated the active ones from the inactive ones. The criterion for "active" here doesn't mean still being able to make calls or send SMS, but rather that the number can still receive OTP codes via WhatsApp or Telegram.
Second, check the registration status on the official Kemkominfo website. Every prepaid SIM card number in Indonesia must be registered under the owner's name. Dina checked her numbers one by one through the official portal. This is important to ensure that the number she wants to use is indeed still registered under her own name, not someone else's that she has forgotten.
Third, reactivate with minimal credit. Some operators allow reactivation of expired SIM cards by topping up with a minimum of Rp5,000 to Rp10,000. This credit doesn't have to be used for calls. It's enough to "revive" the number's status in the operator's system so it can receive incoming messages, including OTP codes.
Fourth, use it for two-step verification. Once the number is active again in the sense that it can receive SMS or incoming calls, the next step is to register that number on the desired platform. Dina primarily uses these numbers for additional WhatsApp Business accounts and Telegram accounts she needs to manage her buyer community.
Challenges Faced and Their Solutions
Of course, this process wasn't without its hurdles. Dina faced several main challenges that required creative solutions:
Periodic verification issues. Some platforms like WhatsApp periodically request re-verification, especially if there's suspicious activity or a device change. Dina overcomes this by always updating the number on the same device to avoid triggering the platform's security system.
Limited number of cards. Not everyone has a stack of old SIM cards like Dina. For those who don't have enough old cards, the alternative is to buy new, inexpensive SIM cards and then not fully activate them. Just a minimal top-up is enough to keep the number status active.
Risk of number deactivation. If a number is unused for a very long time, operators have the right to permanently deactivate it. Dina mitigates this by backing up her important numbers and using them at least once a month for light activity.
Dina's Achievements in Six Months
Within six months, Dina managed to save an estimated Rp1,200,000 that she would have otherwise spent on buying new virtual numbers. Additionally, she gained a clearer understanding of the workflow of an online business that uses separate numbers for each need. Here's a summary of her achievements:
- Saved Rp200,000 per month on virtual number costs that no longer need to be purchased.
- Successfully operated five WhatsApp Business accounts with different numbers without significant additional costs.
- Able to neatly separate communication with suppliers, resellers, and retail customers.
- Reduced the risk of her main account being blocked by not mixing business and personal activities.
"At first, I thought old cards were completely useless," Dina admitted. "Turns out, as long as we know how to manage them, seemingly worthless resources can still provide great benefits."
When Is This Method Still Relevant, and When Are Alternatives Needed?
It's important to understand that this method of utilizing old SIM cards has a shelf life. Each number has a specific life cycle, and after a certain point, it will become completely unusable. Dina herself admits that out of fifteen cards she tried, only eight were successfully reactivated perfectly.
For larger-scale or long-term needs, a more structured solution is still necessary. This is where professional services like complete vacant number (Nokos) services at Nexus SMM become relevant. This platform provides virtual numbers that are already verified and ready to use without the hassle of manual activation processes. It's very useful for businesses that require many numbers in a short period.
However, for individuals or small business owners who want to start with minimal resources, utilizing old SIM cards remains a viable option to try. There's no harm in trying as long as the numbers used remain under personal control and do not violate the applicable platform terms.
Dina's Tips for Those Who Want to Try
Based on her experience, Dina shares some practical advice for anyone who wants to try a similar method:
- Always record the IMSI and ICCID number of each card in a dedicated notebook or spreadsheet to avoid mix-ups.
- Periodically check the registration status of numbers on the official Kemkominfo portal to ensure data security.
- Use a message management application like a multi-SIM manager to facilitate managing multiple numbers on a single device.
- Do not use these numbers for activities that violate platform terms, as the risk of blocking still exists.
Currently, Dina doesn't just utilize her own old cards. She also helps her fellow small business owners in her community do the same. "I'm happy to share this knowledge because not everyone has the budget to keep buying new numbers," she said.
What's interesting about Dina's story is the proof that creativity in managing existing resources is often more valuable than seeking expensive new solutions. Not everyone needs premium virtual number services. Sometimes, the answer is already in our desk drawers, waiting to be rediscovered.
