Product Information

Identification

Physical Information

Product Identifier Summary

Model Number

The model number identifies the underlying Galaxy A05 hardware family and regional configuration. It is useful when checking firmware, network bands, manuals, replacement parts, cases, repair information, and compatible accessories.

MPN

A Manufacturer Part Number identifies a specific commercial configuration, often including region, storage capacity, and color. A complete Samsung sales-code suffix for this exact package is omitted because it could not be verified consistently.

UPC

A Universal Product Code is a 12-digit barcode used for retail inventory and product matching. A package-specific UPC is omitted because the exact international bundle barcode was not verified.

EAN

An EAN is an international barcode used in retail and distribution systems. International Galaxy A05 variants can use different EANs depending on market and packaging, so no value is assigned here without exact verification.

GTIN

A Global Trade Item Number is the broader product-identification system that includes UPC and EAN formats. The number must match the exact packaged configuration rather than only the underlying phone model.

ASIN

The ASIN identifies the specific online catalog record used as the research starting point. It distinguishes this 128GB, 4GB RAM, Black SM-A055M/DS package from other Galaxy A05 variants.

ISBN

ISBN identifiers are intended for books and certain published works. They do not apply to smartphones.

Technical Specifications

Product History

The Galaxy A05 belongs to Samsung’s entry-level Galaxy A smartphone family and entered regional markets during the 2023 product cycle. It followed earlier budget Galaxy A models while retaining a large display, expandable storage, and a high-capacity battery.

The Galaxy A05 is separate from the Galaxy A05s. The A05s uses different hardware, including a higher-resolution display and other configuration changes, so cases, specifications, and model numbers should not automatically be treated as interchangeable.

Samsung released the Galaxy A05 in several regional variants with different model suffixes, storage combinations, RAM capacities, and colors. The SM-A055M family is associated with Latin American and other international-market configurations, while the exact commercial suffix varies by country and distributor.

Buying Considerations

International Model Status

The SM-A055M/DS is an international configuration. Buyers and researchers should distinguish hardware compatibility from carrier approval because an unlocked phone can still be rejected by a carrier’s activation system.

4G Rather Than 5G

The Galaxy A05 supports LTE but not 5G. Users comparing models should distinguish it from newer Galaxy A-series devices that include 5G radios.

4GB RAM

The 4GB RAM configuration is designed around ordinary smartphone workloads. Heavy multitasking and demanding games can place greater pressure on available memory.

128GB Storage

The 128GB internal capacity provides substantially more space than lower-capacity configurations. The microSD slot can further expand storage for supported photos, videos, audio, and files.

Display Resolution

The 6.7-inch screen is large, but its 720-by-1600 resolution is lower than Full HD displays used on some other smartphones. Screen size and resolution should therefore be considered separately.

No Documented Fingerprint Sensor

Samsung’s Galaxy A05 specification does not list a fingerprint sensor. Users who require biometric fingerprint unlocking should distinguish the Galaxy A05 from other Galaxy models.

Carrier Compatibility

The LTE band set includes frequencies used by multiple networks, but band overlap alone does not guarantee activation or all network features. Carrier IMEI verification remains important.

Regional Warranty

International-model warranty coverage may differ from local-market Samsung products. Service eligibility should be checked according to the device’s original region and sales documentation.
