Samsung’s mid-range roadmap for 2026 is quietly taking shape, and the latest signal comes from the Global Certification Forum. The upcoming Samsung Galaxy A37 5G and Samsung Galaxy A57 5G have both appeared on GCF certification, revealing one of the most important things Alertify readers care about: connectivity.

While certifications rarely give us glossy marketing details, they are often the most reliable early indicators of how a device will behave in the real world. In this case, the listings confirm that Samsung is doubling down on global network compatibility, advanced 5G support, and full eSIM readiness across its A-series lineup.

For frequent travelers, digital nomads, and anyone tired of juggling SIM cards, this matters more than megapixels or design tweaks.

Model Numbers, Variants, and What They Tell Us

The Galaxy A37 5G appears under model numbers SM-A376B and SM-A376B/DS, while the Galaxy A57 5G is listed as SM-A576B and SM-A576B/DS. The DS suffix confirms dual-SIM support on both devices, something Samsung has made standard in many international models.

Each phone also carries a unique GCF reference number. The Galaxy A37 5G is listed as 13519, while the Galaxy A57 5G appears as 13529. These identifiers help validate that we are looking at two distinct models, not regional variants of the same phone.

More importantly, the certification confirms support for both a physical SIM (removable UICC) and an embedded SIM (non-removable eUICC). That combination is increasingly becoming the sweet spot for modern smartphones, especially for users who rely on travel eSIMs or want to separate work and personal lines without carrying two devices.

Global Connectivity Takes Center Stage

Both the Galaxy A37 5G and Galaxy A57 5G share an identical connectivity profile according to the GCF listing, and it is a broad one.

They support legacy GSM and WCDMA networks, along with HSDPA, Enhanced Uplink (EUL), and a long list of LTE FDD and TDD bands. This includes widely used LTE bands such as 1, 3, 7, 20, and 28, as well as region-specific bands like 12, 13, 17, and 66, ensuring compatibility across Europe, North America, Asia, and beyond.

On the 5G side, Samsung is clearly positioning these devices as truly global. Both phones support 5G NR standalone (SA) and non-standalone (NSA) modes through EN-DC. The supported 5G bands include n1, n3, n5, n7, n8, n20, n26, n28, n38, n40, n41, n66, n71, n77, and n78.

This band coverage is notable because it aligns closely with what we see on flagship-level devices, not just budget mid-rangers. For travelers, it means fewer surprises when landing in a new country and scanning for local networks or activating an eSIM plan.

eSIM, NFC, and Secure Payments Are Fully Onboard

One of the more interesting confirmations from the GCF listing is the presence of an embedded Secure Element paired with NFC on both models. This hardware-based security component is essential for secure, contactless transactions and protected data storage.

In practical terms, this means smooth and secure support for services like Samsung Wallet and Google Pay. For users who rely on their phone as a travel wallet, boarding pass holder, and payment device, this is no longer optional.

Combined with eSIM support, this setup makes both the Galaxy A37 5G and Galaxy A57 5G well-suited for international travel, roaming alternatives, and app-based connectivity services. It also signals that Samsung sees eSIM not as a premium-only feature, but as a baseline expectation even in the upper mid-range.

Performance Insights

Beyond connectivity, both devices have already appeared in the Geekbench database, offering a glimpse into their internal hardware.

The Galaxy A37 5G is expected to run on Samsung’s Exynos 1480 chipset, paired with 6GB of RAM and Android 16 out of the box. This configuration suggests a focus on efficiency and balanced performance, targeting users who want reliability rather than raw power.

The Galaxy A57 5G, on the other hand, steps things up significantly. Geekbench listings point to the Exynos 1680 SoC, coupled with 12GB of RAM and Android 16. This places it firmly at the top end of the A-series, competing directly with performance-focused mid-range phones from brands like Xiaomi, OnePlus, and Motorola.

Battery and Charging Details Emerge

Battery information has also surfaced through TUV certification. The Galaxy A37 5G is listed with a 4,905mAh battery and support for 45W fast wired charging. That combination is increasingly standard in this segment and should translate into solid all-day usage with quick top-ups.

The Galaxy A57 5G shares the same 45W charging support according to TUV, although its battery capacity was not disclosed in that listing. However, additional information from Chinese certification suggests a 5,000mAh battery, aligning it with market expectations for a device of this size and class.

TENAA Reveals Galaxy A57 5G Design and Hardware

Out of the two, the Galaxy A57 5G has gone a step further by appearing on the TENAA database. This listing confirms a 6.6-inch FHD+ display with a resolution of 1080 by 2340 pixels, along with a slim 6.9mm profile and a weight of 182 grams.

TENAA also lists an octa-core processor, up to 8GB of RAM with 256GB of storage in at least one configuration, and a triple rear camera setup consisting of a 50MP main sensor, a 12MP secondary sensor, and a 5MP tertiary sensor. A 12MP front camera handles selfies and video calls.

Other confirmed features include an in-display fingerprint sensor, standard onboard sensors, and the aforementioned 5,000mAh battery. While this does not tell the full story, it positions the A57 5G as a clean, modern, and very competitive mid-range device.

Conclusion: What This Means in a Crowded Mid-Range Market

Samsung’s approach with the Galaxy A37 5G and Galaxy A57 5G reflects a broader trend we are seeing across the smartphone industry. Connectivity, especially global 5G support and eSIM integration, is becoming a primary differentiator, not an afterthought.

Compared to rivals like the Xiaomi Redmi Note series, the OnePlus Nord lineup, or the Motorola Edge models, Samsung is clearly leaning into certification-heavy, globally compatible devices that work out of the box in more countries with fewer compromises. For travelers and business users, this matters more than marginal performance gains.

The confirmed eSIM support across both models is particularly significant. As more operators, MVNOs, and travel connectivity providers shift toward digital-first onboarding, phones that treat eSIM as a core feature rather than a bonus are simply more future-proof.

Based on reliable sources such as GCF, Geekbench, TUV, and TENAA, it is clear that Samsung is not reinventing the A-series, but it is refining it in the right direction. If pricing stays competitive, the Galaxy A37 5G and Galaxy A57 5G could become some of the most practical mid-range smartphones for globally connected users in 2026.

The official launch may not be teased yet, but all signals suggest it is not far off.
