Following record growth last quarter, the UK mobile market took a step down to just 0.9% growth in the quarter to December on the back of increasing pressure in the business market and the impact of out-of-bundle limits. 2019 looks set to be a tough year for the sector with: a series of potentially painful regulatory hits; markedly lower price rises than last year; and early signs of a degree of creeping competitive intensity. We view 5G as a much-needed means of expanding capacity in the sector with upsides from M2M and IoT likely to remain relatively small.
