Claro delivers best mobile network experience in Brazil

Brazil State of Mobile Networks

June 3rd 2020

Claro consistently offered the best mobile experience to its customers, according to Tutela’s new 2020 State of Mobile Report in Brazil, which was released today. The report found that the operator offered its users the highest Excellent Consistent Quality performance in the country, with 72.2% of tests meeting the “Excellent” thresholds that Tutela uses to represent a group of higher-intensity use cases including 1080p video streaming, HD video calls or mobile gaming. Claro also had the fastest download and upload speeds in the country but narrowly lost out to TIM for best latency, a measure of the responsiveness of a network. 

Tutela has evaluated 21 billion records in Common Coverage Areas across Brazil, including more than 220 million speed tests and 2.8 billion latency tests, collected between November 1, 2019 and April 30, 2020.   


Key findings from this report include:

  • Claro dominated in four of the five metrics in Common Coverage Areas of Brazil, including having the highest Excellent Consistent Quality percentage at 72.2%.
  • TIM had the best latency in Brazil with a one-way result of 19.2 ms, and the second best upload speed, with only 1.1 Mbps separating the operator from first place Claro. 
  • The 1800 Mhz and 2600 Mhz LTE bands are both widely used by all four operators in Brazil, with Oi being the unique operator with an almost 50/50 split of the spectrum. 
  • Oi may not have won any awards this time, but the operator was not far behind on the Core Consistent Quality metric by only 6% behind Claro and 2.5 Mbps behind Claro on the upload speed metric, showing it can step up to the plate for its users on the simpler tasks of internet usage. 


Leandro Demarchi, Sales Director for Tutela in LATAM and Southern Europe, said: “All four operators in Brazil continue to show us excellent results. It is very encouraging to see that at a time like, now where connectivity has never been more important, subscribers in Brazil have such a strong pool of operators to choose from. Although Claro dominated in four of the five metrics tested, the close competition from the likes of TIM and Vivo shows the competitive offerings on hand in the country. We look forward to seeing what this country could do with utilizing 5G technology in the near future”. 

Tutela measures network quality based on the real-world experience of actual network subscribers, inclusive of occasions when a network or plan may be throttled or congested, or when a subscriber is roaming onto another operator’s network. As a result, this report is representative of the mobile experience of a variety of real-world users delivered by each network provider, not the best-case performance of the network itself.
