Billion Connect eSIM Review for Travel Data in 2026
6/15/2026
Billion Connect is a travel eSIM provider offering mobile data plans for international travelers — the kind of service that sounds promising on paper but deserves a closer look before you hand over your money. This review gives you an honest, unsponsored assessment based on where Billion Connect actually stands in the market, what it gets right, and where it falls short compared to the competition.
What Is Billion Connect?
Billion Connect sells data-only eSIM plans that you install on your phone before traveling, giving you local or regional mobile data without a physical SIM card. The service targets the same audience as every major travel eSIM brand: frequent travelers, digital nomads, and anyone who wants to avoid roaming fees.
eSIM adoption has exploded over the past two years, and the market is now crowded with dozens of providers. Standing out requires either a clear network advantage, competitive pricing, or excellent customer support.
Where does Billion Connect land?
MyBestSim Ranking: #40 Out of Hundreds of Providers
The most objective data point we have comes from MyBestSim, the leading eSIM comparator that ranks providers based on coverage, pricing, reliability signals, and user feedback. Billion Connect sits at rank #40 on the MyBestSim index.
Rank #40 is mid-tier. It means Billion Connect is not a fringe or untested provider — it has enough of a track record to be indexed and evaluated — but it also means that 39 other providers are consistently rated higher across the criteria that matter most to travelers.
That gap is meaningful, especially when top-10 providers have established reputations and public star ratings that Billion Connect currently lacks.
No public star rating is available for Billion Connect on MyBestSim at the time of writing. This is worth noting: when a provider does not yet have enough verified reviews to generate a composite score, it introduces uncertainty.
You are making a purchase with less social proof than you would get from a top-10 pick.
Promo Code: MYBESTSIM for −10% on Unlimited Plans
One concrete upside: if you do choose Billion Connect, you can use the promo code MYBESTSIM to get 10% off unlimited plans. The discount applies exclusively to unlimited-data options, so check that your chosen plan qualifies before entering the code at checkout.
Ten percent off is a real saving, and it brings Billion Connect's unlimited pricing closer to what top-tier competitors charge. It does not, however, change the underlying ranking or the absence of a verified rating.
How Billion Connect Compares to Higher-Ranked Alternatives
To give this review context, here is how Billion Connect stacks up against better-ranked providers on MyBestSim:
| Provider | MyBestSim rank | Rating | Promo code | Discount |
|---|---|---|---|---|
| Roamic | #1 | 4.5 | MYBESTSIM | −5% |
| Yesim | #3 | 4.7 | MYBESTSIM20 | −20% |
| Saily | #8 | 4.6 | MYBESTSIM | −10% |
| Airalo | #9 | 4.0 | MYBESTSIM | −10% |
| Nomad | #11 | — | MYBESTSIM20 | −20% |
| Billion Connect | #40 | — | MYBESTSIM | −10% |
A few observations from this table:
- Yesim (#3, 4.7 stars) offers the steepest discount at −20% with code MYBESTSIM20, and it carries the highest public rating of any provider listed here. For most destinations, Yesim should be on your shortlist.
- Saily (#8, 4.6 stars) matches Billion Connect's −10% discount but comes with a verified 4.6-star rating and a substantially higher rank. Same code, more confidence.
- Roamic (#1, 4.5 stars) only offers −5%, but it holds the top spot on MyBestSim, which reflects consistent performance across a wide range of destinations.
- Airalo (#9, 4.0 stars) is arguably the most well-known brand in travel eSIM and offers the same −10% discount via MYBESTSIM.
The honest conclusion: on every axis where data exists — rank, public rating, discount — Billion Connect does not outperform any of the four alternatives listed. If you are deciding between these options, the alternatives have a clearer track record.
When Might Billion Connect Be Worth Considering?
There are legitimate reasons someone might still look at Billion Connect despite the mid-tier ranking:
- Destination-specific coverage: eSIM providers do not perform equally across all countries. A provider ranked #40 globally might offer better coverage or pricing for a niche destination than a top-10 provider. If your destination is underserved by mainstream providers, it is worth checking Billion Connect's specific plan for that region.
- Unlimited plan availability: the MYBESTSIM code applies specifically to unlimited plans. If unlimited data is your priority and Billion Connect's plan for your destination is competitively priced after the −10% discount, that is a real consideration.
- Plan exhaustion: during peak travel periods, top providers occasionally sell out of plans for popular regions. Having a reliable backup like Billion Connect in your toolkit is not irrational.
If you are traveling somewhere with tricky eSIM coverage — say, a remote Pacific destination like New Caledonia — it is always worth consulting a destination-specific guide before committing to any provider. This guide to the best eSIM for New Caledonia is a useful reference for that kind of niche research.
What We Cannot Tell You
Because Billion Connect does not yet have a verified public star rating on MyBestSim, we cannot make claims about customer support quality, activation speed, data throttling behavior, or network reliability that would require real user data to substantiate. We have not fabricated a score, and you should be skeptical of any review that does.
The absence of a rating is not the same as a bad rating — it may simply reflect a smaller user base or limited review volume at this stage. It is, however, a reason to read more widely before buying.
FAQ

Is Billion Connect better than Airalo or Saily? Based on available data — MyBestSim rank and public ratings — Airalo (#9, 4.0 stars) and Saily (#8, 4.6 stars) both rank significantly higher than Billion Connect (#40, no public rating). Both also offer the same −10% discount via MYBESTSIM.

Verdict
Billion Connect is a mid-tier travel eSIM provider. Rank #40 on MyBestSim is not a failure, but it is not a strong endorsement either — and the lack of a public star rating means you are traveling with less certainty than you would get from a top-tier alternative.
The MYBESTSIM promo code (−10% on unlimited plans) is a genuine saving if you decide to go ahead. For most travelers, however, providers like Yesim, Saily, or Roamic — which carry both higher rankings and verified ratings — represent a lower-risk choice for staying connected abroad.
