Phoenix Tower International has completed the acquisition of 3,700 mobile sites in France from operators SFR and Bouygues Telecom, according to Data Center Dynamics. The transaction closes a sale-and-leaseback process that moves a substantial slice of French passive infrastructure into independent hands.

The figure matters. At 3,700 sites, the deal represents one of the larger single tower portfolio transfers recorded in the French market. SFR and Bouygues Telecom remain anchor tenants in the standard infrastructure-sharing arrangement that underpins such transactions.

What does the completion change for operators?

For SFR and Bouygues Telecom, the completed sale converts fixed infrastructure assets into capital while locking in long-term tenancy on the same towers. Operators across Europe have used this model to fund 5G rollout without carrying passive asset depreciation on their own balance sheets. The two French operators now lease back the sites they previously owned.

For Phoenix Tower, the acquisition adds scale in a market where it already competes with established tower players. Independent towercos live on tenancy ratios — the number of operators sharing each mast. A 3,700-site portfolio with two guaranteed anchor tenants provides immediate contracted revenue and room for additional colocation.

Why does the timing matter?

The completion lands as French operators continue dense 5G deployment and prepare for future network generations. Tower monetization has become the standard financing lever across European telecoms. Operators facing heavy spectrum and rollout costs increasingly treat passive infrastructure as an asset class better held by specialists.

France has been among the more active European markets for such transfers. Multiple operators have sold portfolios to independent infrastructure funds over recent years. Each transaction deepens the separation between active network equipment, which operators retain, and passive steel and fiber, which investors now own.

What are the practical consequences?

For practitioners, the completed deal changes three things.

• Colocation negotiation. Operators seeking access to these 3,700 sites now negotiate with Phoenix Tower rather than with SFR or Bouygues Telecom directly.
• Site rollout planning. Future upgrades on these masts follow the towerco's build and modification timelines.
• Market concentration. Independent tower ownership in France grows, which affects how wholesale access terms develop across the sector.

How large is the portfolio in context?

A portfolio of 3,700 sites would, if each mast served a typical coverage footprint, address millions of subscriber connections across urban and rural France. The exact financial terms of the completed acquisition were not disclosed in the source report.

Phoenix Tower has not stated publicly what share of its total French footprint the 3,700 sites represent. The company continues to operate its broader European portfolio alongside the newly acquired French assets.

What comes next?

The completion removes the final regulatory and contractual steps from the transaction. Attention now shifts to execution — how quickly Phoenix Tower can raise tenancy ratios on the acquired sites, and whether SFR and Bouygues Telecom deploy the freed capital into their 5G build programs.
