Acer has revealed the specs of its new Liquid E1 and Z2 phones, only days before the start of the Mobile World Congress in Barcelona, Spain.

The E1 is a mid-range phone with a 4.5-inch qHD display and 1760mAh battery. It packs a dual-core 1GHz processor and runs Jelly Bean — and most importantly, has both single- and dual-SIM configurations. Acer's "Float" software will prevent notifications from popping up during videos, and can blast sound out of two DTS speakers.

The E1 offers 1GB of RAM, plus both front- and back-facing cameras. It also comes with 4GB of internal storage and a microSD slot for optional expansion.

The Z2, an entry-level offering, has similar specs but a smaller HVGA screen at 3.5 inches, 1300mAh battery and 512MB of RAM. It also comes with single- and dual-SIM options, as well as a choice between a 3-megapixel or 5-megapixel camera. It has the same 4GB of internal storage and microSd card.

Acer's software allows the cameras to shoot continuously for up to 99 shots, and both smartphones are able to connect to AcerCloud, its in-house "file-sharing and media management solution," the company says in its press release.

While these numbers aren't quite as impressive as some of the monster smartphones hitting the market lately, such as Samsung and HTC among others, Acer's phones are competitively priced. The E1 will cost between €199 and €229 while the Z2 will run between €99 and €129, Engadget reports.

Both phones are slated for release in France, Belgium, the Netherlands and Ukraine, then Russia, Italy and the UK.

This announcement comes in the wake of HTC's long-awaited press conference Feb. 19, at which it announced its new HTC One. The One received rave reviews after a hands-on section, many emphasizing its Ultrapixel camera, which would allow for better photos in dim lighting.
