Exhibit 99. 1

Sonim Technologies Reports First Quarter Financial Results

Austin, Texas – May 14, 2020 – Sonim Technologies, Inc. (Nasdaq: SONM),a leading U.S. provider of ultra-rugged mobility solutions designed specifically for task workers physically engaged in their work environments, reported financial results for the first quarter ended March 31, 2020.

First Quarter 2020 Highlights

• Net revenues were $12.7 million

• Gross profit was $2.2 million

• GAAP net loss totaled $10.0 million

“We are hopeful that the first quarter will be the trough in ouron-going transformation of Sonim into a growing rugged mobility business driven by a leaner, lower cost team focused on the path to profitability,” said Tom Wilkinson, Chief Executive Officer. “Like most businesses, theCOVID-19 pandemic caused some disruption to our operations in the first quarter, including a three-week closure of our factory in Shenzhen, and will continue to have an impact on our supply chain. Despite these challenges, we are expecting an increase in demand in the second quarter and can now focus on quarterly sales to a broader range of carrier and enterprise customers.”

“While theCOVID-19 pandemic continues to generate a great deal of uncertainty in any forecast, we presently anticipate revenue and gross margin improvement in the second quarter, relative to the first quarter, while maintaining our focus on lean operations and cash efficiency. Additionally, operational changes implemented over the past few months have enabled the company to grow its cash balance to $12.4 million at the end of Q1 2020. This added liquidity will help the company drive future product development.”

COVID-19 Impacts

Sonim experienced a shutdown of its manufacturing facility in Shenzhen, China for approximately 3 weeks in Q1 as a result of theCOVID-19 pandemic. As of March 31, manufacturing operations were once again fully operational. Sonim has implemented safeguards in its facilities to protect employees, including increased frequency of cleaning and disinfecting facilities, social distancing practices and other measures consistent with guidance from local health authorities.

Sonim’s other global teams are complying with work-from-home andshelter-in-place requirements while continuing to support deployments to first responders and public safety workers. Sonim has been designated an Essential Supplier by a major US carrier that provides critical services to ensure first responders, emergency responders, public messaging, 911 communications and other critical communications remain functional. Select Sonim staff have traveled to support critical deployments of Sonim mobile devices for emergency management services and other agencies.

First Quarter 2020 Financial Results

Net revenues for the first quarter of 2020 decreased 52% to $12.7 million from $26.5 million in the first quarter of 2019. The decrease in net revenues was primarily attributable to lower volumes of devices sold due to one key US carrier that completed a prior minimum required purchase agreement in 2019. Sonim is now selling through existing inventory in collaboration with that carrier while also increasing sales through other customers and channels. Sonim expects the carrier to complete the sell through of existing inventory and become a purchaser of additional devices again in 2020 as it continues to expand its business with the Company.

Gross profit for the first quarter of 2020 decreased to $2.2 million (17% of net revenues) from $9.0 million (34% of net revenues) in the first quarter of 2019. The decrease in gross profit was primarily attributable to overhead related to the temporary shutdown of our manufacturing facility in Shenzhen in Q1 2020, aone-time event which artificially increased cost of goods in the quarter.

Operating expenses for the first quarter decreased by approximately $2 million as compared to the prior year first quarter, and by approximately $3 million excluding restructuring charges. This reflects our ongoing work to reduce operating costs.

Net loss for the first quarter of 2020 totaled $10.0 million or $(0.48) per basic and diluted share (based on 20.6 million shares), compared to net loss of $5.1 million, or $(0.32) per basic and diluted share (based on 15.8 million shares), in the first quarter of 2019.
