How to Save Money on SIM – 10 Proven Tips
If you feel your mobile bill is “stuck in traffic” and won’t go down—you’re not alone. The thing is, in 2025 you can use mobile services much more smartly and pay less, without giving up on data, without getting stuck without coverage, and without surprising fine print. It’s not magic: it’s a mix of personalization, the right tools, and a bit of awareness.
That’s exactly why I gathered here the 10 most effective tips that have saved my clients hundreds of shekels a year (and for some, even more). We’ll touch on prepaid (Tokman) vs. postpaid, eSIM, roaming, virtual numbers, device settings that reduce consumption, and small tricks that make a big difference. Ready to slash costs? Here’s how—simple as that!
By the way, if you want a smart one-stop comparison, to check plans or make an easy prepaid SIM purchase—the ZolSim platform centralizes it conveniently and quickly.
1) Real needs mapping before buying – “How many GB do you actually need?”
Most people buy a plan based on ads, not usage. That’s a mistake that almost always costs money. Open your provider’s app or your phone’s Data Usage and check: how much data you used over the last 2–3 months, how many call minutes, and what your WhatsApp/TikTok/YouTube pattern looks like. You’ll be surprised to find that a “huge” 300GB plan is unnecessary if you’re on Wi‑Fi most of the day.
Another angle: some prefer “peace of mind” with a big allowance, but in practice there’s no difference in experience between 50GB and 150GB for the average user. If you’re not downloading heavy video files and not doing constant hotspotting, a mid-size allowance with stable speeds gets the job done—and saves tens of shekels every month.
Field tip: for clients who run the three-month lookback, the rate of “downsizing” to a smaller plan hits 60%+. Meaning? Immediate savings starting next month, without feeling a difference in day-to-day use.
2) Tokman (Prepaid) or monthly plan? Choose the payment model that serves you
Tokman (Prepaid) is pay-as-you-go—no commitment and no overage charges. A monthly plan is a fixed bill, usually “unlimited,” with possible extra charges for overages or add-on services. Asking “which is cheaper?”—the answer depends on usage patterns, not slogans.
If you’re parents of kids, soldiers, or users with highly variable consumption, Tokman gives control and visibility. For those who need an “always-on” line and have stable usage, a monthly plan is economically sound. Compare not only price, but also the fine points: real-world speeds, network coverage where you live, and whether there are unnecessary blocks (e.g., certain VoIP infrastructures).
A quick table to make sense of it:
| Type | Best for | Advantages | Disadvantages | Potential savings |
|---|---|---|---|---|
| Tokman (Prepaid) | Kids, soldiers, tourists, seasonal use | Full spend control, no surprises, can pause | Must top up on time, sometimes less “GB per shekel” | 15%–40% vs. an underused monthly plan |
| Monthly plan | Steady use, work, business lines | Convenience, “unlimited,” port-in promotions | Indirect commitment, possible overage fees | 0% if optimized; loss if oversized |
| Hybrid (bank of minutes/GB) | Variable use | Partial flexibility | Can be complex to understand | 10%–25% with proper fit |
P.S. On ZolSim you can quickly compare Tokman vs. monthly based on real usage patterns, including options for immediate Tokman top-up.
3) eSIM: less plastic, more flexibility—and often savings too
An eSIM is a digital SIM loaded to your device without a physical card. Why can it save money? First, no need to swap SIMs for short trips (e.g., abroad). You can buy a local digital eSIM and load it remotely—no need to buy a physical card at the airport.
For Dual SIM devices, eSIM lets you manage a work and personal line in parallel, or an Israeli and a foreign line—enabling and disabling as needed. That reduces sticking with pricey “just in case” bundles, because you only activate when you need it and pay only when you use it.
From experience: tourists arriving for a week or two save around 20%–35% by choosing a local eSIM in advance compared to buying at airport counters. Just check device compatibility and activation method (QR/app), and make sure the plan includes an open APN for tethering if that matters to you.
4) Roaming abroad: not every minute is worth a euro—buy smart and save big
Most providers will gladly sell you a “global roaming bundle” at an apparently convenient price. In practice, a local eSIM/SIM in your destination is usually cheaper and offers more data and speed. Yes, even if you need WhatsApp and navigation—you don’t have to pay double for “peace of mind.”
Rhetorical question: why pay 99–129 NIS for a week of roaming data if in Europe you can buy a local 20–30GB bundle for less? Tourists in Israel? Same logic—a short-term local SIM will significantly reduce spend, especially if you need local calls.
Field trick: if you’re crossing multiple countries, look for regional eSIM bundles (e.g., Europe)—they’re often better value than piecing together per-country bundles. Save even more by pre-downloading over Wi‑Fi (offline maps on Google Maps or Here WeGo, playlists, etc.).
5) Calling abroad? Switch to VoIP and virtual numbers instead of pricey talk bundles
Common myth: “International calls require a special, expensive plan.” In reality, VoIP services (internet telephony) and virtual numbers do it cheaper, often with better quality, especially over Wi‑Fi or stable 5G. Small businesses also benefit from flexibility: receiving calls from various countries on local numbers, without roaming costs.
For personal users—if most of your communication is on WhatsApp, Telegram, or FaceTime Audio, there’s almost no need for international minutes bundles. Keep local minutes simple and cheap, and add VoIP as needed. Small money, big effect.
From client experience: dropping “international minutes” bundles and replacing them with VoIP + one-off add-ons for rare cases cut monthly spend by 15%–25% without hurting reachability. Just check your provider doesn’t block VoIP protocols in the plan (most plans in Israel don’t, but it’s worth asking).
6) Speed vs. volume: you don’t always need 300GB—sometimes you need a stable 30GB
Another marketing trap is to wave huge data allowances when what really matters is stability and real-world speed where you actually use the phone. Check 4G/5G coverage where you live, work, and commute. What’s 200GB worth if practical speed drops to 3–5 Mbps during peak hours?
A trick I like: flip the approach. Set a “minimum speed budget” (say 20–50 Mbps) and then pick the cheapest plan that meets it, even if the allowance is smaller. You’ll get a better experience and pay less.
On many devices you can restrict background data for apps and limit video to 480p/720p. A small drop in video quality saves tens of GBs a month. One user who switched YouTube to 720p saved ~40% data—suddenly a 50–70GB plan was “plenty.”
7) Kids, soldiers, and tourists: profile-tuned Tokman—control without drama
For a kid’s line, the real needs are WhatsApp, light browsing, and school calls. A Tokman with a mid-size data bundle and limiting unnecessary outgoing calls brings order. The parent controls spend, the kid doesn’t “burn” minutes on nonessential calls, and the family avoids overage fees.
For soldiers, the issue is concrete buildings on base and spotty coverage. Tokman lets you top up only during periods/locations with coverage and pause when there isn’t—without paying for a “dead” month on a postpaid plan. This seasonal usage pattern saves quite a bit. Add a WhatsApp-only or zero-rated chat add-on if available—sometimes it’s a fair deal.
Tourists in Israel benefit by landing with a ready eSIM or buying a local SIM with a generous allowance for a week or two. Don’t be tempted by “unlimited calls” if you’re mostly on WhatsApp. Options like ZolSim curate especially good short-term bundles for visitors.
8) Smart number porting, negotiation, and retention: make the carrier work for you
You won’t believe it, but… a lot of money is saved in a single phone call. Customers who tell their provider they’re considering porting out often get much better offers than what’s on the website. It’s not magic—it’s customer retention. Just come prepared with market alternatives.
Do your homework: compare prices, speeds, coverage, and terms. Present a few current offers and set a clear “target price.” If you don’t get it—port out. Israel is a relatively easy portability market, and the switch usually takes just a few hours.
Practical tip: better deals often land at month/quarter-end when targets pressure the reps. Yes, it works in mobile too. Also ask for small perks: an extra SIM at no charge, free eSIM activation, or a discounted first month. Over time it adds up.
9) Dual SIM: combine two lines and save smart
A Dual SIM device (or physical SIM + eSIM) enables smart splitting: one line with ultra-cheap data, and a second with voice/ business number features. Instead of paying a premium for “everything in one,” you pay a little for two lines and get the best of both worlds.
Example: cheap data at Provider A with 100GB, and voice/telephony at Provider B with a landline-style number. Result: 20%–35% savings vs. a single “mega-bundle.” Set in your phone which SIM is default for calls and which for data, and switch with a tap as needed.
Another advantage: when one line “chokes” in a specific area, the other sometimes works better. It’s no substitute for checking coverage before buying, but in the field it provides redundancy that reduces “dead time” and boosts satisfaction—without paying for a pricier plan.
10) Savings maintenance: monitor balances, block wasteful usage, and top up smart
No less important than the initial choice is the upkeep. Install your provider’s app and set threshold alerts: 70%, 90%, and near-overage. When you get an alert—check what “ate” the GBs: video? TikTok? app updates on cellular? Fix and move on.
On Tokman, set a fixed top-up schedule and avoid last-minute, high-priced top-ups. Look for “bonus top-ups”—some providers grant extra data when topping up above a certain amount. On platforms like Tokman top-up you can do it digitally without chasing physical stores.
One more small thing that makes a big difference: block heavy automatic downloads on cellular (system updates, cloud backups, photo/video uploads in original quality). On most phones, you can set those to Wi‑Fi only. Result: fewer overages, fewer headaches.
Common myths—busted (briefly)
- “Cheap = poor coverage”: Not accurate. In Israel, networks are shared and many operators ride the same antennas. Check local coverage and real-world speed—not the brand name.
- “eSIM is pricier than a physical SIM”: It depends. In many cases, eSIM for travel is cheaper and more convenient, especially short-term.
- “‘Unlimited’ always saves”: If you aren’t a heavy user, you’re paying an unnecessary premium. A measured, fast plan is often better.
